Dear Members,

I am searching for advice to use the Table(T,c) function for material properties. I am using CCM+ v13.02.

Problem: I want to make a new Material Database and define the material properties with the Table(T,c) table but I get an error and there is no description in the manual about how has to be this table.

See structure here: Picture1.png

And if I do a right click on the "Test(liquid)" this window comes up, where some properties can be defined with Table(T,c):

See Picture2.png

The manual explains what is the Table(T,c) but doesn't describe how the input table has to be and which entries are requires. Has anyone an idea how the table has to be? I get an error when loading in the table, saying that there is an error due to the columns.

See Picture3.png

Thank you!

It's been a while since I used the user-defined property tables like this, but IIRC...


Say you have a table defined for temperatures 300, 400, 500, 600 K

and pressures 1, 2 kPa

and you wanted to show densities at each point (I'll just say 1-8). Then the table would be formatted with all 8 points as:


T(K),Pressure(kPa),Density(kg/m^3)
300,1,1
400,1,2
500,1,3
600,1,4
300,2,5
400,2,6
500,2,7
600,2,8

This way each variable in the table is a single column. Be careful with the unit, if it is not recognized I believe star will treat the number as SI, but like I said it's been some time so please verify yourself that your table is being interpreted correctly.
