Hello,

I want to simulate the stresses of a material thats Youngs-Modulus is dependent on temperature and humidity. I implemented the behaviour in the engineering data with a user defined field variable "humidity" and inserted my data.

Now I want to do a transient structural analysis. For each node I have the temperature and the humidity in a txt-file. The txt-file is structured als follows:

node ID | x-coordinate | y-coordinate | z-coordinate | temperature_time_step_1 | humidity_time_step_1 | temperature_time_step_n | humidity_time_step_n |

Via external Data I imported the temperature as a imported Body temperature and chose the right temperature-column for the right time step. This works fine.

Now I want to import the humidity via external data draged to the model of the transient structural box (see picture Bild1). Here I have a problem. I cannot chose a time step for the humidity (see picture Bild2). Is there a way to get the time step into the humidity via commands or so? What command do I have to use? Manipulating the structure of the txt-file is not a problem in case it has to be changed.

I hope you can help me.

Kind regards
