CCM+ bad_alloc
 
Does anyone know anything about "bad_alloc" errors in starccm+?? Occurs when I try and run the model. What could be causing this? How do I prevent it?! Thanks

save your model after meshing. shutdown ccm+ and then restart it.

bad_alloc is the standard c++ out of memory error. It probably failed to allocate enough space for the solution data.

As TG wrote, if you just generated the mesh, re-starting may allow you to proceed. If not, you may need more memory or a smaller mesh (fewer cells).

Now THAT sounds like something Micro$oft would offer you as a solution to bad code!

In fact this problem is worse on windows for various reasons. Try googling "heap fragmentation windows" ...
