Design of vent system

If anyone is aware of computer programs to aid in design of of mitigation systems could you kindly share that information.

The NY State Radon Program became aware of potential requirement of for a municipality code that states: “The sizing, design and layout of the vent system shall be permitted to be determined by [approved] computer program design methods which shall be approved by the commissioner to insure compliance with the minimum standards of this code.”

Thank you for any input.
