      This error message is due to a wrong memory estimation, which can occur for long thin meshes, e.g. large differences in dimensions. As workaround the interpolation can be started from command-line with the following command: cfx5interp -dest name.def -res name.res -mxl By default, is set to 1/3 * (No. of vertices in the definition file), so try a number 10-100 times higher.
