Default Interpolating mesh (CFX-10.0)
Posts: n/a

I have memory problems when I try to interpolate the results from a previous solution onto a new mesh in the solver manager. The interpolation fails during initialisation with an insufficient memory error message. I am doing the interpolation onto a mesh consisting of 2 million hexas and 1.2 million tetras, and I am doing the interpolation on a master node with 1.5Gb RAM working in double precision. The run is performed in parallel, so I have no memory problems during the "normal" run. The memory problems are only occurring during the initial interpolation procedure.

What is the problem? Do I somehow need to allocate more memory to the interpolation procedure? Or is it just physically impossible to perform the interpolation of a mesh of the mentioned size on a 1.5Gb maschine?

any suggestions are welcome

regards, CFDworker

It depends on whether the message relates to physical memory, or allocated memory. If it's physical, then you have no memory left on the machine. If it's allocated, then it may be that the interpolation program is simply not allocating enough memory for your particular case.

There are some command line options for interpolation that are not available through the Solver Manager GUI. If you type:

cfx5interp -help

at a command prompt, you should see a number of command line options for the interpolation program, one of which (-mc I think) is a memory allocation parameter. This may or may not help your case.

Hope this helps,
