Combine Derived Results

Altair Forum User

Hello to everyone,

 

This is a very easy question, but I have not found out the way to do it, so I decided to ask you.

 

I have computed a simulation of a plate with some forces on it, and, as usual, I have the displacement field at each node (I will call this variable, which is a vector, Disp).

 

Now, I compute this derived result: V1 = 2*Disp. I do it as usual, in the expression builder I select variable 'Displacement'.

 

Then, I have in the vector tree a new variable called V1.

 

Again, I would like to calculate a derived result involving this new variable V1, for example, S1 = dot[V1,Disp]. And here is my question: When I try to select in the expression builder the variable computed previously, I can not find it. So, do you know how can I make a computation over the derived results computed previously?

 

I know I could do it at the same time (S1 = dot[V1,Disp] = dot[2*Disp,Disp]  = 2*dot[Disp,Disp]), but I would like to learn how to do it separately in order to do more complex computations between different loadcases.

 

Thank you in advance!

Hi @Angelito

I dont see a way to include derived results in functions.

 

I will check with experts on the same and will provide any workaround to you soon.

Hi @Angelito

 

So far I did not have a workaround, I will raise a RFE to add such feature if possible.
