mapFields problems

Hi,
I used "mapFields -consistent" successfully to map my first mesh results on a new finer mesh.
When I restart the job I have "floating poit exception".
I saw in new mapped mesh some strange point (see the figure attached). I think because in old coarses mesh where now is air, was surface! So here I got 0 value and I obtain "floating point exception" (I have not "nan"). Is it right?
Then I tried "mapFields" without "-consistent" but I obtain:

Cannot find cutting-patch fixedWalls in destination mesh

Could anyone aid me?

Thanks in advance

Seems likely that you get the floating point exception due to some point that get unphysical values after the mapping. It would be nice with a OF utility that allows the user to bound scalars with some min() and max() function (setFields?). A way to do that manually would be to import the (ascii) data into matlab and use the functions there... seems a bit messy, but could still save time if it takes long time to obtain the mapped fields.

Good luck
