Simulation live gives results as zero

SoretteMichel — Wed, 02 Jan 2019 10:29:25 GMT

Hi everyone and happy new year,

I've started the Simulation Live trial program and while following the introduction course, i'm running into a strange issue : results stays at zero for any restriction/load i might try.

In the information message area, i'm getting this message : The material library is not available in the current working directory or the application data folder.

I've commented my usual pro_material_dir option to make sure i'm using OOTB material library. I've also tried to copy the library or the applied material file in the working directory without success.

Thanks for any help on that topic.

Hi Michel,

This issue will likely appear if Creo cannot find the Material folder used by the Ansys Solver.

Can you please check if you see the MaterialLibrary folder under the following location?

C:\Users\<USERNAME>\AppData\Roaming\PTC\Creo

When you assign a material to a model and run the analysis, it will be syc'd in this folder. You would just use your regular materials as you would normally do. If that folder does exist, delete it and then start Creo again and give it a try. This will recreate the MaterialFolder automatically.

This is not likely to do with your graphics card. If it was an issue, you would not have been able to start the analysis.

If that is still an issue, let me know and we can jump on a teleconference to sort it out.

BTW....are you using the build from ptc.com or from this group? I updated the build in the group to the production version of Creo 5.0.3.0 which contains the early access version of Creo Simulation Live.

Thanks

Mark

Hello,

I am getting a very similar behaviour. Except, I don´t get any messages in the information message area at all. It just evaluates everything to zery. It doesn´t matter whether I take the introduction course part or one of our company parts. Changing the material didn´t help, deleting the materials library folder didn´t help either. Is there already a solution known for this issue? Graphics driver was updated for Simulation Live, it didn´t recognize it before.

It would be great if someone could help me.

L3mming,

A couple thoughts. Are you putting a fixed support someplace? If you don't have a fixed support, then the behavior you are seeing would be zero results.

Can you start a session of Creo with no configuration files? So rename all your config.pro, config.sup, customization.ui files and restart Creo. This would help rule out some unknown behavior that a config setting is causing.

Hope one of these suggestions gets you results,

Todd Kraft

Hi ToddKraft,

thank you for your suggestions and such a quick reply to my question. As for the fixed support, I use the very same boundary conditions as I do for our production parts using standard Creo Simulate 2.0, so this is very unlikely to be the reason. In the test parts of the Simulation Live tutorial I use the suggested boundary conditions. Regarding your other tips, I use a clean, new installation of Creo 5.0.4 with evaluation licenses. Creo shouldn´t use any customized configuration files, as it is not started through our company launcher and thus should use the default files. Nevertheless, I tried it and unfortunately didn´t have any luck. Any other suggestions?

Hi L3mming,

The next step should be for us to get together on a Webex to see what is happening and then I can troubleshoot further. Can you email me at tkraft@ptc.com and we can setup a time?

Thanks,
Todd Kraft

Hey everyone,

same problem here. Is there a solution yet?

Thanks

Re: Simulation live gives results as zero

L3mming — Wed, 05 Jun 2019 10:29:32 GMT

Not yet, at least not for me. I talked to Todd and we couldn´t find the reason for this issue, so we agreed that I´ll try it out on a PC of a colleague of mine. My colleague has administrator privileges while I don´t. We´ll see whether this solves the isse.

One strage fact is, that I can run thermal analyses without a problem, but modal and structural analyses evaluate to zero. Can you try a thermal analysis on your machine? Just to see whether it is the same problem or a different one.

Greetings,

L3mming

Duplo — Wed, 05 Jun 2019 10:54:15 GMT

I just tried thermal analysis and it works!

Structural and modal don't.

I got local admin rights on my machine.

I will do some more testing.

L3mming — Wed, 05 Jun 2019 11:01:35 GMT

Okay, so at least we seem to have the same problem, which is good for finding a solution. I hope Todd will see this and get in touch with you. I´m curious, are you also working on a notebook and had to install the latest Nvidia drivers for Simulation Live to start up?

Re: Simulation live gives results as zero

Duplo — Wed, 05 Jun 2019 11:05:26 GMT

Yes, I' m also working on a notebook.

Running a NVIDIA Quadro M1000M

Driver's date: 05.05.2019

Version: 26.21.14.3064

Re: Simulation live gives results as zero

L3mming — Wed, 05 Jun 2019 11:13:12 GMT

Im using the exact same Driver, Nvidia 430.64 (26.21.14.3064).

But I´m running a Quadro M2000M. Can you try downloading and installing the previous release of the Nvidia Drivers? Unfortunately I cannot try this myself because of permissions.

Hello everyone,

This is how i solved it myself : i've redefined all my environment variables related to caches management as in the attached picture.

It appeared that the system was supposed to write and read data in some place and having those variables not defined properly created some issues.

Not sure it will solve it for you but it worked well for me.

Regards,

Duplo — Wed, 05 Jun 2019 12:48:44 GMT

Thank you. But for me sadly it doesn't work.

Tomorrow I' will try another driver even though I don't think thats the issue.

Re: Simulation live gives results as zero

L3mming — Wed, 05 Jun 2019 13:29:00 GMT

Unfortunately it didn´t work for me too.

I also cannot think of why the graphics card should be the problem, but who knows...

Re: Simulation live gives results as zero

Duplo — Wed, 05 Jun 2019 13:42:39 GMT

I did a clean installation of creo, did no changes beside the .psf for the licence.

I also installed R430 U3 (430.86) (26.21.14.3086).

Still the same problem.

Don't know what else I could do.

Re: Simulation live gives results as zero

L3mming — Wed, 05 Jun 2019 14:32:29 GMT

I´m sorry for that. But I´m also puzzled by that problem, just as the people at PTC. When I installed it I also had a clean Installation, nothing changed except the .psf for the license. At first it didn´t start at all until I got the lastest driver. With that new driver it started the plugin, but it only works in thermal mode.

What I meant is maybe an older driver works. Something like release 410 or 418.

Re: Simulation live gives results as zero

L3mming — Fri, 07 Jun 2019 14:31:20 GMT

I finally solved the problem. The reason was the Nvidia graphics driver. Going back to release 418 solved it, so now it´s working. I hope this will help you too and brings you good results. Mine are within 17% deviation at maximum accuracy settings.

Re: Simulation live gives results as zero

Duplo — Tue, 11 Jun 2019 04:36:19 GMT

YOU, are my personal Hero!

I switched back to the last QNF-Driver which is R415 U2 (416.78) and it works for me too.

Problem solved!

I am just running through the tutorial and seeing the same message "The material library is not available in the current working directory" in the log file. I can see no sign of any Material Library folder in the AppData folder being created. Have you any suggestions.
