  Hi
  
  I have a dynamic mesh model which I have defined the time dependent mesh deformation via a UDF. with a coarse mesh my UDF is compiled without any problem. but when I increase mesh quality, I can not compile my UDF via Fluent. when I press "build" to create library, after a while I see below message:
  
  fatal error C1128: number of sections exceeded object file format limit: compile with /bigobj
  
  does anyone know how can I fix this problem?
  
  thanks in advance

  It would require adding a compiler flag (bigobj) by hand and then compiling by hand. I cannot tell more here on this open community. Provide an eligible university address.
