HI everybody, I have a probelm with fluent simulations. I have meshed and exported my 3d grid, but when I start the simulation, the simulation doesn't start, but it says: "floating point error:invalid number temperature limited to 1 in all cells of the domain" absolute prerssure limited to 1 in all cell of the domain. is this a grd problem?I mean a mesh problem? can you help me? thanhs a lot antonietta

it does not sound like a mesh problem, to check this try to make a very very coarse mesh for the same geomtery, and do the calcualtions on it first, if u get the solution (may not be very accurate) then go on to the finer mesh and this time follow the same things , if u still get the errors then it is a mesh problem.

if i were you i would probably check the models or boundary conditions i am using, and if it is related to boundary conditions and models, fluent gives the same warning when we initiate the case,

You may check if the grid is correct or not through Grid -> Check.
