Default transient compressible flow simulation-urgent

Hai to all,

I am doing compressible flow simulation. In this, the flow rate is continuously varying with respect to time. Massflow rate is zero for some time and it is suddenly increased to peak level. Then it will continuously reduce in nature.

My problem is when the mass flow attain the peak value, i got following errors.

turbulent viscosity is limited to 1e5 temperature and pressure limited to ....

I cannot use the initial solution, because at starting time the flow rate is zero.

Any idea to solve this.

Thanks in advance

with regards JSM
