vumat_nh.f error

[tsmsngi]

Dear all

I had the following error when I use the input file named case01_ABAx.inp and
vumat_nh.f to check the system validity for user subroutine of ABAQUS/Explicit.

/opt/abaqus/6.8-1/exec/package.exe: symbol lookup error: /tmp/root_test_6528/libexplicitU.so: undefined symbol: __svml_powf4

I can not solve this problem.

I did ABAQUS verification and all of the items are passed.
My OS is SUSE Linux enterprise 10.
I'm waiting for your help.

many thanks

dear all

I solved this problem.
When I put write statement in the vumat_nh.f, I could run ABAQUS.
But I have one question that this is suitable solution or not?

anyway thank you for all.
