Hi All, i have a 3D case and i am trying to make a new domain with bigger downstream length, i already tried Fieldconvert to interpolate my old field to use it for the new 3D case and i done it in this next command line ============================ FieldConvert -m interpfield:fromxml=mesh_old.xml:fromfld=2Dmean.fld mesh_new.xml newfield.fld ============================ and i have error ==================== Segmentation fault (core dumped) ==================== I tried also to use mean field as a 2D file and made field interpolation and i have the same error any suggestions? Thanks,
