How to convert weldments frame to solidpart so i can simulate it in to simulating express?

I make frame using weldments fitur. After triming the end profil, I want to run my frame for simulating to get structure analysis. I tried to combine the profil per item so all of them were combined. When i ran simulating there was meshing in combine. And i tried to reduce meshing but it couldn't success. So do you have any idea to solve probem, who i can run the simulating to be success??

Create an IGES file, open this and combine the solids to create a single structure, then use that in Simulation.
