Time Varying BC
 

Hi,

I am facing a problem in giving Time varying stagnation BC's. Actually I am trying to give time varying Stagnation Temp. and Pressure. I am trying a transient analysis. Please tell me the parameter that needs to be used varying properties with time. I know 'DT' represents the actual timestep given but the problem is that I couldnot find the variable that gives me the time elapsed i.e. sum of 'DT'.

Thanks

A.S.
