mpirun noticed that process rank 0 with PID 19125 on node r00n13 exited on signal 8 (Floating point exception).

The GAMG/PCG matrix solver is running into a situation where in trying to solve the equation it is obtaining a value that can't be expressed as a float. In simpler words, it is most likely getting a division by 0 because either the boundary conditions or the initial conditions or your tolerance are not correct.

Hi I am trying to run a user-defined spectrum in waves2Foam by modifying wavesProperties


the error is as follow
