Hi,

The model heat source is a discrete data point imported in text format by ansys workbench external data module. The imported data are in 4 columns, namely x, y, z and heat generation rate, respectively. How to make this heat source change its loading position in the model over time and calculate the transient temperature distribution of the model? What I came up with was to transform the local coordinate system with the heat generation rate in it over time. How do I implement the idea in ansy sworkbench.

I would also like to ask whether the local coordinate system of the imported heat generation rate data can add a time parameter, thank you.

I have seen CFD users import , for example, heat transfer coefficient and fluid wall temperature as a function of time from CFD and apply it to a FE mesh using External Data and Mechanical. To do this you create multiple files - one for each time point. In External Data you can import multiple files (representing different points in time). You can point to one of these as a master file so that the interpolation is not carried out every time. Since the mesh is not changing, the interpolation function created for the first time can be reused if you mark it as master.

 

Then in Mechanical you can indicate which file will be used at what time point (analysis time).

On the other hand you can search for "moving heat source ansys" in Google and you will some Youtube videos including one that has APDL script shown for defining a function of x,y,z,time.
