After a modeled structure is defined with applied loads,
00:07
you can run several different analysis types on the structure.
00:12
In this example, a linear static analysis will be run
00:17
with the model open from the text menu, select analysis calculations,
00:23
the calculations, dialogue displays
00:26
and immediately begins loading the analysis
00:29
after a brief moment.
00:31
If no warnings or errors occur,
00:33
the dialogue closes,
00:36
be aware that the analysis is still possible
00:39
if warnings occur
00:41
but it is not possible if errors occur.
00:44
Once the analysis is complete
00:47
a notice that results fem
00:50
available
00:51
appear both at the top and bottom of the program.
00:55
Each load case combination
00:58
will now have computed stresses and strains
01:01
based on generalized section forces
01:04
to inspect the results
01:06
from the toolbar,
01:08
expand the cases drop down
01:10
and select either a simple load case
01:13
or a combination load.
01:15
In this case,
