[CIG-SEISMO] forrtl: error (72): floating overflow with SPECFEM2D

[junhuahu_CAS]

Hi Dimitri and Paul,
      I conducted a test using SPECFEM2D. There is no error if I use the mesh 200*200. But if I increase the elements to 
400*400 , the programm will encounter a problem and display the following information. I have run it on 24 Processors with MPI

So how can i fix this problem? The attachments are the input files. 
Besides, how can I choose the proper dt and mesh size to avoid the numerical dispersion? 
thanks for your help

Best wishes
