Hello,
Is there a way to combining load cases in Simulation, but only when using beam mesh/beam elements? I know that combining is possible in module "Pressure Vessel Design" in case solid or shell elements, however this module is not supported for beam mesh/beam elements.
what is the application?
is there a reason you can't apply the loads all in one study?
Hello Jared,
Combination of load cases are used in the design of buildings, bridges. For these structures we try to simplify the calculation model by creating model with beam elements. Based on this we can calculate the internal forces (M, V, N) onto the structure needed to design according standards. Combination of load cases serve for verification of the various extreme cases that may arise during the life of the structure(wind load, vertical load, self weight, fire load, different position of load......). In the case that it is not possible to use combinations of loading cases, the load must be calculated with using of superposition, manually.
For example: Standard combination. Standard combination consists of loading cases, which are multiplied by a safety factors. For example, the safety factor of the building in normal service of building is high, but in case of fire is very low because it is considered that the building has less people. So it is necessary to make more combinations that we consider all the effect on the design. In more complex structure you can have tens combinations.
In attached picture is example of one combination and table of safety factors.

so why not apply all the loads in one study and then control the variables with a design study?
Hello,
I´m also wondering if it´s possible to define load cases in the non-linear analysis to describe a load history under real conditions. This means computation of a load case with lateral forces and when this computation is finished a following computation with the vertical loads, but still in one continuous computation. I know it´s possible to create load cases in atena but I haven´t found useful information about it in solidworks simulation.
My second question is if there is an option to define computation jobs to let the computer work on new models as soon one model´s analysis is finished. I try to let the computer to run overnight to work on the results the next day.
Thanks for your respond!

first question > yes, that is the beauty of nonlinear, you can "sequence" analyses
second question > yes, take a look at the run all option or task scheduler
Hello Stefan Gavura,
are you sure that it is not possible to perform load combination with beams? I have made this on a mixed model with solids, beams, and shells.
you're right leo, that limitation isn't listed. maybe older version/service pack had that limitation?
2014 SolidWorks Help - Pressure Vessel Design Overview
or maybe the OP wants stress linearization?
Hi Stefan,
We cannot disclose any details about the next release here... but I suggest you to login in the SolidWorks 2015 beta forum. You might find something interesting there.
Cheers,
Alex
