Hi Everyone,

I am trying to use a variable of vapor concentration C_v with respect to T in COMSOL....

Such as

(2.8e-20*T^10[1/K]-4.9e-17*T^9[1/K] + 3.5e-14*T^8[1/K] -1.4e-11*T^7 [1/K] + 3.3e-09*T^6 [1/K] - 4.9e-07*T^5 [1/K] +4.4e-5*T^4 [1/K] -0.0023*T^3 [1/K] +.061*T^2 [1/K] -.061*T^2 [1/K] -0.64*T [1/K] +1.1) [kg/m^3]

however it is showing error there (yellow sign). For your kind consideration I have attached the picture of error herewith.

Can anyone please give me a direction how to write down the variable with respect to temperature?

Best Regards

Soma
