Hello to everyone!


I have a problem in the thermophysical properties section. The viscoisty of my material has a polynomical change, so I need to use the logPolynomial model for the transports properties, nonetheless, OpenFOAM says that the combination of properties is not available and that there is not any combination with logPolynomial available.


Does anybody know how can I implement the logpolynomial model, as the polynomial is not precise enough?


Thank you for your attention.

Hi!


There is a logPolynomial (https://openfoam.com/documentation/g...t.html#details)
The reason for that error is that you can't combine freely the thermoTypes. In the error it should print the combinations for you.
(For example if I remember well, polynomial thermo with const transport is not possible, while polynomial thermo and polynomial transport is possible. I think you got the idea.)

Yes, but in the list of thermoTypes there isn't any combination with logPolynomial transport available.
