FATAL_ERROR: [1087] temp_bound area wrong

Amin_ · December 13, 2024, 11:25

Hi,

In the FSI simulation, when I change the boundary type from "TWO_D" to "TWO_D_AXIS" it gives me this error:

FATAL_ERROR: [1087] temp_bound area wrong

However, there are no issues when running this case without FSI or TWO_D boundary type ...

I would appreciate any suggestions for fixing this.

Sincerely,
Amin

Hello Amin,
There are a few conditions your simulation must meet before you can go ahead and switch from TWO_D to TWO_D_AXIS type. They are as follows:
1) Your TWO_D_AXIS boundaries must be normal to the z axis
2) You may not have any vertices in your surface geometry for which their x coordinate is less than zero
3) The axis of symmetry must be the y axis
4) The boundary conditions for the boundaries on the x=0 plane must be of SYMMETRY type

Kindly verify that these conditions are met by your simulation and get back to us if you are still having problems.

Hi Amin,

Can you check if your entire domain is on the positive x-axis. If this does not work send your case setup to support@convergecfd.com.

Hello, friends!

Yes, it finally worked! Thank you so much for your guidance and support. I truly appreciate it. You’ve made me incredibly happy, and I wish I could repay your kindness in some way.

After carefully reviewing all the points you mentioned, I realized the only mistake I made was assuming the axis of symmetry was along the X-axis. Before simulating the FSI, I was skeptical about the results, but now everything is perfectly correct.

I’ve completely fallen in love with Converge, it’s simply amazing.

Wishing you all a blessed, successful, and joyful New Year. Thank you again for everything.
