Hi:

I met a problem for the variable heat source. For example, the fire in the building can be taken as heat source in the simulation. But at the first stage, the heat power is: Q=a*t**2, Q is heat power, a is a constant, t is time. Only the linear heat source with time is given in software. How can I defined t-square heat source in the simulation.

Thank a lot! Li Y

Use the UDF DEFINE_SOURCE
