Neumann condition for temperature in only one direction

[mmagain]

Hi Yvan,

I switched to code_saturne V8.0 for simplicity as you suggested. The code now compiles but I get a SIGSEGV. I investigated the issue but I was unable to find what was wrong. Do you have any idea what might be wrong ?

Best,

Michael

Hello,

I have been able to investigate further and it's really weird. I pinpointed the problem being with trying to do operations with double and cs_real_t (I think). For example

The code runs successfully if I write

Code: Select all

double dT_loc = T_loc; //Here T_loc is defined by cs_real_t T_loc = T[face_id] which does not cause sigsegv when isolated

but when I add one line to print dT_loc or do an operation with dT_loc like shown below I get SIGSEGV...

Code: Select all

double dT_loc = T_loc; 
cs_real_t hlv = 2257.*pow(dT_loc, 2.5); //This causes SIGSEGV,

I am really lost.

Best regards,

Michael

Hello,

When behavior gets really strange like this, it probably means that there is some sort of error upstream of where the crash appears.

When switching to v8.0, did you align the user-defined function ? There may be a change in the arguments (a tool such as meld can be useful for this).

Otherwise, compiling a debug build (using --enable-debug) and runnning under Valgrind may help.

Best regards,

Yvan
