As I start the simulation of bubble column (air-water system), just after 15 iterations, it displays "floating point exception" and shows "divergence detected in AMG solver". Inserted the _clearfp() followed by _controlfp_s() functions which clear and mask the FP exceptions before attempting any floating point operation. EDIT: Having a look at the case itself, please remember that for DSMC you … A "floating point number" is how computers usually represent numbers that are not integers -- basically, a number with a decimal point. Underflow: result so close to zero that some precision was lost.
The biggest differences arise in the treatment of floating-point exceptions. The problem with your blockMeshDict file is that you are not following these rules: The local coordinate system is defined by the order in which the vertices are presented in the block definition according to: the axis origin is the first entry in the block definition, vertex 0. 2020 · numpy allows one to handle IEEE-754 exceptions originating from floating-point by using appropriately. 2020 · The given code is rewritten as follows to handle the exception and find its type. For example, verify that the NOPRINT option is not used. Unlike the FSAVE/FNSAVE instructions, the processor retains the contents of the FPU, MMX and SSE state in the processor after the state has been saved.
