Yes, there is an option in ABAQUS also. As I have never used it, I will not be able to give detailed information. I will suggest you to look for the keyword *IMPORT in Abaqus keywords reference manual, that should give you sufficient information.

Unfortunately Abaqus does not have a solution yet. Import analysis also is a bit tedious and you might run into errors with that. In case you know all the load cases forehand, then maybe define them as subsequent steps (Step-2, Step 3, Step 4....) in a single calculation. it might save a lot of time since the mode based calculations are linear.

Thank you Anshul and Sivaraj for your answers. Let me go to details. I have a large model which takes 3 days with my best PC to finish modal analysis and about 10 days for random analysis. I have various random and shock analyses with different directions and different loading frequency ranges. The point is I want to run modal step once and use it several times for different analyses to save 3 days for each analysis. 

Output of an analysis can be used for another by importing but in here the second analysis considers the modal step and go to it once more. I am not still sure whether there is a way or not !

:(

Hi, 

I will still suggest you to look at *IMPORT option in ABAQUS. One of my labmate has succesfully used it for a problem.
