With the commands “CALC” and “APPL” the computing effort can be reduced, otherwise I don’t know of any method to implement a brute force algorithm. Try to
Please have a look a the chapter 3.1 Input Language and the the stated commands within the ELLA manual.
(source: SOFiSTiK ELLA manual, page 3-1)
Furthermore you can reduce the runtime of ELLA with the following tips.
Switch off the output generation (ECHO FULL NO) or generate a reduced output. Do not use ECHO LPOS only if it is absolutely necessary. Reduce the number of elements in the evaluation (options FROM TO INC in command CALC). In case of a system where the bridge deck is made from area elements (QUADs) use INT 3 instead of 5-9 in command LSEL.
I hope these tips help you.
