  Hey
  I am writing a udf and I want to say “if fluid is not porous, do x”.
  I know if the fluid is porous it says this
  if (THREAD_VAR(t).fluid.porous). But I want the opposite. Is there anything for this?
  
  Thanks for the help,

  You can use an if else statement or just using the negation "!".
