NASTRAN-95 vs MYSTRAN
#1
It is relevant to compare MYSTRAN to NASTRAN-95 and also discuss the state of NASTRAN-95.

-----------------------------------------------------

NASTRAN-95 (Advantages):
- More developed and includes aero and fluid elements.
- More history of use (more well known)
- The buckling solutions are more developed (MYSTRAN only supports beam elements for Eigen solutions).
- DMAP capability

NASTRAN-95 (Disadvantages):
- The user manual may need updates.
- Some of the element formulations are old (i.e. shells may exhibit shear locking).
- The code may be difficult to develop, but there may be a few developers who can work with it.
- The solver that is used may be outdated by today's standards (considering the solver is at least 25 years old).
- No PSHELL or PCOMP?

NASTRAN-95 (Unknowns):
- There appears to be some nonlinear analysis capability, but the extent is not known. Need to investigate the MATS1.

-----------------------------------------------------

MYSTRAN (Usability)
- A compiled version for Windows exists.
- The state for Linux is less known, but a compiled version exists (may be an older version).
- For both cases, we are reworking how it is compiled so that is can be used with gFortran.

MYSTRAN (Advantages)
- Perhaps the biggest advantage of MYSTRAN is developers should find it more user friendly.
- Created with more modern software and hardware in mind.
- User manual is complete and updated
- Newer solvers can be incorporated with relative ease

MYSTRAN (Disadvantages)
- Not as developed or well known as NASTRAN
