I typed in my icoFoam simulation ... but during the solution of the problem for me a strange error occurred ... could someone help me?

Exceção de ponto flutuante (imagem do núcleo gravada) MY OBSERVATION>>>GOOGLE TRANSLATOR Exceção de ponto flutuante (imagem do núcleo gravada) = floating-point exception (core image recorded) ANYONE KNOWS WHAT THIS MEANS?? HOW TO FIX IT?? THANKS ALL! |
