FDS Mesh Size Calculator

This tool allows you to easily generate a MESH line for input into Fire Dynamics Simulator (FDS) v5. It automatically finds the optimal (Poisson-friendly) mesh division numbers and returns the complete mesh line to be pasted into an FDS input file.

For more information, see the FDS 5 User Guide Section 6.3 or visit the official NIST FDS Website
