Automatic Combinations - Seismic Qua Comb not recognized

The automatic combination dialog recognize the seismic quadratic combination only if it was requested through "Analysis type --> New --> seismic --> direction --> resolution of force... -->quadratic comb".

 

If it is supposed to be created after generating the three directional sesmic loadings then the program doesn't recognize it as a valid case to be further combined through groups and relations.

 

Am I missing something?...

 

PS: the behavior of the automatic combination is unstable once the Generate button is hit. It simply crash way to often - although I checked the behavior of automatic combinations on a very basic model (just a cantilever). Unfortunately the error is not reproducible as it appears quite erratic.

Please send a sample rtd file and indicate what combinations you would like to have generated.

Please start with basic action which is deleting temp files and restarting the OS.

Please find attached the sample file. Combination 7 (Comb_Qua1) is not visible as a basic case in "Load Case Code Combination" --> Cases Tab. Therefore, cannot be selected for further combinations.

I use Robot 2013.

 

I finally managed to reproduce the error. Use the attached model and then please select "Loads --> Automatic Combinaton --> More --> Relations" --> Generate - then the program freezes.

thanks, it works.

 

But, what was the reason for the first step? it doesn't make any sense to me...

 

The "comb_qua1" combination has been already set the right way.

I don't know how you created this example and as far as I can see you are using your own regulation file. As the comb 7 was not listed I made sure its nature was correctly assigned (this is linked to the regulation file used in the example). My job was purely solution seeking for the situation I was put  into Smiley Happy

I was just curious and I switched to Ec.rgl but nothing's changed... Anyway, I have to remember reseting the nature in future to stay trouble free. Thanks.
