hello. I'm writing because I have a problem with the .op2 file.
When performing mode analysis using sol103, the .f06 file and .op2 file are created without any problems, and all data are included. File size is also more than 300 kilobytes.
However, in the case of sol145, the .f06 file contains...
Hi, I am modeling a wing with strip theory for flutter analysis.
In the case of the doublet lattice method, there is a precondition that the size of the aerodynamic panel should be less than 3 at subsonic speed and an aspect ratio of 1 at transonic speed or higher.
Is there such a condition...
According to the Nastran manual, to analyze the flutter with the pk method, the reduced frequency must be entered with the mkaero command. When entering mkaero, I know that it can be obtained by entering the mode frequency from sol103 and v_min and v_max.
1. If you look at .f06 analyzed by the...
thank you for Advice!! sol103 was performed for flutter analysis. May I ask additional questions?
As you said, in many papers the analysis mainly considers translation only. However, some consider rotational components as well.
When is rotation information considered? In my analysis result...
hello. I am doing modal analysis with SOL103 of MSC Patran/Nastran.
If the displacement result of mode 1 is selected after analysis with Nastran, it is divided into rotation and translation as shown in the picture below. Can I superposition this movement as a single movement?
Looking at the...
