ViewFactor Gen Malloc crash?

pupo · August 22, 2016, 07:33

Hello Foamers,

I'm trying to implement the view factor model in a small wedge model, however, when running the viewFactorGen command i get the following error:

Code:

Total number of coarse faces: 24
*** Error in `viewFactorsGen': malloc(): memory corruption (fast): 0x0000000000cffb40 ***

Any idea how to fix this?

The case files are available here:

Best Regards,
Pedro

Sorry for the late reply, hope you managed to solve it

If there is anyone around who has the same problem, I solve it by changing a number in the viewFactorsGen file and recompiling it again (under a different name, of course).

The change was to write:

labelList triSurfaceToAgglom(20*nFineFaces);

instead of:

labelList triSurfaceToAgglom(5*nFineFaces);

In the searchingEngine.H file.

And somehow the segmentation fault disappeared.
