Re: Simulation Express
Hi Gerhard,
Are you getting any error messages when it fails? Is it getting through the meshing stage?
As far as adding a force or pressure to a particular location probably the easiest way is to create a Split Line on the surface in question. Once you have create a line or new area on the original surface you can choose that to add your load to.

Re: Simulation Express
Hi Gerhard (again)
As far as applying force/pressure/etc to regions of a surface, use <Insert/Curve/Split Line> to create such a region on the desired surface (simple circle example image attached). This creates a new face and you can then apply force/pressure/etc to this new face.
Later... I just did a really quick Sim Express study and it failed! I hadn't saved the simple part that I'd created. I then saved it and it ran ok. Is it that simple? I'll do another trial (i.e. no save then run) and let you know.
Later still... I did another simple Sim Express study and it worked ok first time without saving. What is your experience with this? Can you re-run the study and get it to work or can you never get it to run? You using 2011 or 2010 for this? I'm using 2010 SP4.0 Premium.

Re: Simulation Express
I've managed to create sub surfaces as you've explained (thank you), but all of the simulations continue to fail. Saving does not seem to help. I don't believe the simulations are getting past the meshing as they all seem to fail at around 32% completion.

Re: Simulation Express
I agree with Deepak. probably a meshing issue. See if adjusting the mesh helps, if not you can upload your file if you want and I will try to run it and see what happens.

Re: Simulation Express
I had no luck after changing the mesh and the material several times. But then I saved my beam as a copy, opened the copy tried once more and the simulation worked. So, while I am still confused, I guess I will just continue this process in the future. Thanks for all the responses!

Re: Simulation Express
I've ZIPped my sample Sim-Express study. You should be able to put these three files in a folder and just load the part, then click on Sim Express and it should load the CWR file ok. Just step through the Sim Express until you get to 'Run'. Does it run?

Re: Simulation Express
Keith,
Your simulation ran fine on my machine. I seem to have figured out how to get mine to work. I simply save a copy of the model that I want to run my simulation on and then work with the copy. It seems to work every time. However, if I close and reopen the copy it won't work afterwards. Strange? Yes, but at least a little bit more predictable now.

Re: Simulation Express
Good to have a workround, but clearly not good enough for something that should be really reliable! What does your VAR say?
When you start to use Simulation proper, there'll be loads more head scratching & crashing, I assure you! Good luck.

Re: Simulation Express
Something is obviously not working properly. At least you do have the work around but I would definitely contact my VAR about the problem and try and find a better solution.
Full blown Simulation can cause hair loss but I have to admit that it has become a lot more stable and reliable with fewer instances where you are left wondering why you even bothered trying. One plus about the full version is that you do a little more control over the process which can really help in troubleshooting these types of issues. Much of it is still "hidden" from the user but I find it better han Express. Good Luck.

Re: Simulation Express
Here's my 2 cents... simulation xpress is just flaky sometimes. I've gone as far as renaming my reg files, starting sw again, and sometimes that still doesn't fix it. Sometimes it runs, sometimes not. I could never nail down whey, not repeatable. Even with a simple cube, I couldn't get sim express to run, sometimes...

Re: Simulation Express
Hi,
while running the Simulation express it will save the results in the temp folder.
see the Fig.1 in the word document, did u have write access permission to temp folder?.
if yes, then it will work fine.
If not, change the result location to new location i.e. where the part is saved, see the Fig.2 in the word document.
after completing the results, save the model and close. If you open the model, once you click the simulationXpress module, it will automatically load the results.
Try above option i.e. changing the working directory. It may help. i tried in 2010 and 2011 module. it worked fine.
Thanks & regards,
Ameer.C
