I'm doing a simulation in Explicit Dynamics in workbench and I want to import stress data from the results of another explicit dynamics analysis.

I exported stress results in text format by right clicking on "Normal stress" icon, then opened the text file in Excel and saved it as a .csv file. Then, I did the settings of "External Data system" as it can be see in the picture, and loaded the .csv file in it. Afterwards, in the Explicit Dynamics system I right clicked on "Imported Pressure" icon and chose "Import Load". But I got this error "The data in worksheet is invalid, Please correct before proceeding to import". Can you please help me?

Firstly, try to export node data with node coordinates along with the node IDs.

 

For this change following option from Tools>Option

And check the data type, it should be node ID instead of element ID (If you are sure that the node IDs in newer mesh are the same as older one).

or else import them using node coordinates.

Thank you very much. I have done your suggestions but the problem still exists.

And why the load is imported as "pressure" (without any options to change it) while the exported data are stress? Can it be related with the problem?

sorry, It seems like with explicit dynamics only external pressure is supported as per the help doc.

Thank you for your great help. But another question comes up: Can I use Transient Structural system instead of Explicit Dynamics? My analysis should be done in a 0.00001 second step time.
