Hello,

I am getting the following error for a simulation. Can anyone suggest why is this happening?

process hf3d error: Matrix solver exception: file I/O failure. Please contact ANSYS technical support

Please let us know what version of the tool are you using and also provide some screenshots of the error.
Are you getting this error for only one model or you are not able to solve any model?
All the very best.

Hello I am using version 2020 R1.
I am getting this error when there is not enough RAM space to solve the system. I tried to simulate the design with a different computer with bigger RAM, there it simulates without any issues.
Thanks.

Dear, fparveen

Please, how do you resolve this problem? I have a computer with a lot of RAM, but I'm getting RAM errors.
