Re: Mechanical Simulation running speed
What value have you set for SOLRAM (the Memory Allocation parameter in the Run settings)?Where are your temporary and results files being written?What is your exact CPU model? Single-thread...

Re: Is it a .obj meshable in simulate?
You cannot mesh the file. Why don't you just make a sphere in Creo? Or do you need all those faces?

You may already know this, but if you would like a better understanding of .obj files, read this: https://en.wikipedia.org/wiki/Wavefront_.obj_file

Re: Is it a .obj meshable in simulate?
I believe Steven's correct. I was able to shrink-wrap the .OBJ file to create a solid model that would allow me to apply loads and constraints to model. When I try to assign a material file the system...

Re: Mechanical Simulation running speed
Hello Jonathan, thank you for your answer. I have a local SSD. - SOLRAM is default. I try to set it now to 16 GB. (My RAM is 32GB). Is it OK based on your opinion? - Temporary and result...

Re: Mechanical Simulation running speed
Just to confirm, you have a local SSD and the temporary and results files are located there? Yes, I don't believe there's any problem with having them both in the same place. 16 GB SOLRAM should be...

Roland, Increasing the RAM is something I brought up four years ago to product development, as discussed in the attached thread: https://www.ptcusercommunity.com/ideas/2424

Steven, The locations we want accurate stresses calculated are a small proportion of the total model.We normally have to run with a 'raw' mesh first to get a 'feel' for the behaviourThen we home in...

Roland has two questions in his original post. My thread was just FYI to show you cannot increase the RAM over the allowed limit.

Hi, A (very) long while since I did this but none the less a useful method. I used to do it in Independent and wanted use the method in Creo but can't. A geometrically symmetric model but the loads are...

Yup, there were 2 questions (Jonathan dealt with them adroitly).

Re: Anti-symmetric loading, symmetric geometry
It can be done. If interested: BUT it is less efficient as there are 4 models run rather than 2 as in the old (version 20 and before?) days Create anti-symmetric loadsetsymmetric loadsetanti-symmetric...

Hi Charles, thanks a lot for posting this, since I also recognized some time ago it did not work any more and had no time to try out how it works now. For interested users, I attach an old paper from...

Re: Anti-symmetric loading, symmetric geometry
Roland, I had a rare spare moment and it was annoying me. The Mechanica method was faxed to me (Ronald Fuchs??) at about the time PTC acquired RASNA. It is not as efficient now. Could it be a more...

Hello, thanks for your answers and ideas. I tried to increase the memory allocation to 16000MB but it has no effect on running speed. (It has a very small effect but it is not significant) My main...

Roland, An out-of-the-box install of Simulate will configure the software to use all cores. It is possible to configure it to use fewer. But unfortunately and as Jonathan said, non-linear studies seem...

Re: Pressure Vessel Simulation - "The model is insufficently constrained"
Zach, If you are not using contact and are treating the connectivity as 'free' where the contacts would otherwise be then you can use modal to identify the culprit. Method 1: run a constrained model...
View ArticleRe: Pressure Vessel Simulation - "The model is insufficently constrained"
Thanks for your quick answer. I'm running the Modal analysis right now. The contact interfaces have been ignored and treated as free by Simulate. Everything else is a bonded connection, even though in...
