[CIG-SEISMO] Problems with Scotch in Specfem2D

[Philip Knaute]

Dear all,



After some time using Specfem 2D 6.1.1 with the internal mesh partitioning
routines and without Scotch, I now tried to get the code with the scotch
package to run.

Sadly  was not very successful, as of yet. Compiling Scotch and the
Specfem2D code with 64-bit version of the Intel compiler package 11.1 works
fine, but when I try to run xmeshfem2D I get the error message below:



-------------------------------------------------------------------------------------------------------------------------------------------------------------------



Parameter file successfully read...



 The mesh contains            4  elements



 Control elements have            4  nodes

If I play around with the ‘–DINTSIZE flag’ and ‘-integer-size xx’ for scotch
or Specfem respectively, the code only stops working earlier.

Does anypne experienced something similar or knows a solution for my
problem.

I would be very grateful.



Thank you very much in advance.



Cheers,

Philip
