NX10: Material property change during solution time
NX10: Material property change during solution time
(OP)
Hi there!
I want to specify the temperature dependent thermal expansion coefficient (TCE) of a material in two parts and have it switch from one to the other at a specified time during transient simulation. The specific material has a irreversible TCE during initial firing and after reaching a certain predetermined time, goes irreversible. I have provided a sketch of what I mean attached. So the TCE material property would have to contain an if statement or something, stating that before time = 100 seconds, the TCE value is the irreversible table field and if time > 100 seconds, the TCE value is the reversible table field.
Is this possible? Would there be a better way of doing it?
Warm regards,
Juan

RE: NX10: Material property change during solution time
If (ug_var("time") > 50[sec])
Then(fd("Steel Thermal Expansion Coefficient (A)") )
Else( fd("SS Thermal Expansion Coefficient (A)(2)") )
But it says the field does not match the filter.
The two variables are just copypasted fields from other materials.
