I want to get the heat flux values for a p20 steel solid 2d rectangular shape. I want the values for each node in the y-axis written in a .txt file. Whenever I compiled my udf it builds but when loading I get this error.<\/p>\n

ERROR: The UDF library you are trying to load (libudf) is not compiled for parallel use on the current platform (win64).<\/span><\/p>\n
