CFD Air flow simulation from Autodesk Inventor Assembly

[Anonymous]

Hello,

I am a beginner with Autodesk CFD, but I want to make an Air flow simulation from an assembly I draw with Inventor 2016.

In the attachment you see some pictures of the assembly. This assembly I want to open with Autodesk CFD 2016, but the program is not responding, and crashes every time I want to load this file. I think the file is too big for CFD because there are a lot of patterns in it. I already tried to export the assembly as different CAD formats, like .stp, .sat and .x_t, and I also tried it with a simplified part.

How can I solve this problem?

Thanks in advance!

Sincerely,

Sam

Try just a cube, to be sure the issue is model related.

Then, why not read this in using solid block with no holes and use the 'resistance' material to give your parts the right properties?

I tried it with just a few cubes, so I draw it in Inventor as one part which respresents the air in the whole system.

This video also helped me to solve the problem: https://youtu.be/PgHeW_zIHao?t=12m55s

Now CFD opens it and makes a simulation.

Thank you very much!
