Running error

[Seisstudnet]

Hello.
This is my first time using specfem3d and I get the following error when running it:

Program received signal SIGFPE: Floating-point exception - erroneous arithmetic operation.
Backtrace for this error:

What is the cause of this error? Is it a mesh problem or a source problem? What should I do to solve this error?

Thanks!
