Error opening multi-block grid file

I made a grid in Gridgen and try to use it in Phoenics, when I load the case it gives the error:

" Error opening multi-block grid file
Error number 602 opening block +
**Unknown error code** "

I have 15 structured blocks, some have line domains, poles.

If someone could help me.

You should also contact CHAM user support at and ask them to take a look at the grid files which were produced. There are two 'flavours' of multi-block files supported by PHOENICS - it isn't clear which one is supported by Gridgen.

When Gridgen exports PLOT3D it exports 3D multizone. In other words, the first line of the file is the number of blocks and the indices are all specified I,J,K. You can choose between ASCII/binary/unf and single/double precision. I don't know which of those flavors can be read by PHOENICS.

Gridgen also exports PHOENICS' native file.
