Hi there, 

I'm looking into the fatigue life of a structure under cyclical loading. I have data to input as forces in the x,y,z directions respectively. I am planning on using the rainflow method to input this data and use the fatigue combination tool to determine the fatigue life. 

Is there a way to have 3x inputs of historic data (.dat) files in the same static structural analysis? It seems I can only input 1x .dat file per static structural. Ideally I am looking to have 3x .dat files to represent my x,y,z forces - and then sum the cumulative damage from each one. 

If that is not possible, is there a way to run a seperate static structural for the x,y,z respectively and then sum the fatigue damage from each? 

Cheers, 

Ben

Hey Ben,

Can you explain what you meant by you can only import 1 .dat file into a static structural. Because with external data module or with external model - it will allow you to import multiple files and then link it to your static structural setup.

Let me know if you meant something else.

Thanks
