SQP method for calculating non spherical particles reporting errors

Hello, everyone!
I am using the latest version 23.3 to calculate non-spherical particles. When the particle index m=2 and n=6 is calculated for a period of time, the following error will occur.

But using non-spherical particles with m=2 and n=4 will not result in an error. Do you know where the problem occurred? Thank you!

Please go to the Numerics>Advanced pane and uncheck the floating point exception traps to see if this helps. There are some singularities with SQP calculations that we can sometimes bypass.

Thank you for your reply. I’ll give it a try. @jeff.dietiker
