Dear members
I developed a new solver based on reactingFoam. It was compiled without errors. But when the case was prepared and run It gave the following error. Can someone please help me to solve this.

Floating point exception (core dumped)

Hi,

The error message indicates that it is a floating point exception. I am tempted to say that this is because you are dividing by zero somewhere in your initial calculations.

Cheers,

Hi

Thank You Very Much
I solved the problem. Some boundary field values were set to zero. I corrected the mistake.

Hi Upuli,

Can you tell me what did you do to correct it?

Thanks

Hi

I added some small value 1e-25 to the variables which are divided by volume scalar fields.
