hi I am modeling gas solid flow. In pre I am getting the following error.

" Molar mass needs to be set up for Multi Component cases".I am not able to find out the error.

Please help me. Thanks in advance

Hi Thandavan,

Is your gas a pure gas or a multi-component gas? Do check if the molar mass has been entered for all the components.

Hi hagupta, I have checked for all the compnents. the molar mass is specified. I donot know, still it persists..

Have u also checked the molar mass option for the "Variable composition mixture" that u have used?

Hi, for me one fluid is variable composition kixture and the other is reactive mixture. I cannot set molar mass for the variable composition mixture. am i right. But i have set and checked it. still it is not working..

Any idea you have
