I try to use VBA to read and write a text file without using "Cells". How can I find a "word" in a text file and change this word and output another text file? For example, I want to find all "structural" in the following text file and change it to "nonstructural". Suppose that size of the file...
How to calculate the impact force when an lighter-than-air vehicle performs Vertical Landing? Actually, the vehicle lands vertically on the ground using air cushions. I tried to establish a speed corresponding to the impact forces. The impact forces are obtained from max ground reaction force...
Does PATRAN/NASTRAN have the capability to bond two surfaces of two solids together?
I tried to model an assembly consisting of two parts. The two parts share one surface. How can I glue these two together in order to obtain same nodes and mesh at the bonded surface?
How to write NASTRAN statement for output of safety margin:
MAXMIN (DEF) TTTT (BEAM,10) MAXALG(10) MINALG(10)?
I know the how to write the ourput for stress and forces but don't know which word in NASTRAN is used for safety margin (replacing TTTT in the above statement). I tried to find it in...
I analyze a structure which consist a beam on the ground. I would like to constrain the beam in that way that it can be movable in positive Z direction but immovable in negative Z direction. (Z is vertical to the ground) How do I do that?
From Patran displacment constraint, I can only make it...
How to apply boundary conditions to a 3D truss structure?
As shown in the attached pictures, all the structural members are pinned- connected. CROD element is used to model the truss members. The pink elements in the pictures represent cables. I fixed six DOF of eight bottom nodes: Grid Point...
COSMOS Warning: Ratio of clearance/element size in at least one element is larger than 1. Do you wish to continue?
What can I check with this warning?
I have mixed mesh in my model, both shell and solid elements.
Thank you for any input!
