However, we are working on a generic converted that can covert nodes/elements from one program to another. This is a pre/post that can create finite element models, but not native MYSTRAN decks. Although Mecway is not free, it is low cost. This may be a possible option in the future since pyNastran has some capabilities to do this. A simple mesh converter has been partially developed, but a true translator from BDF to INP (CalculiX/ABAQUS) has not been developed. PreProcessors (Without Native MYSTRAN Support)Īpre/post and has an internal Mecway solver as well. It has only been evaluated on a preliminary basis, but looks like a promising option. It is a free program, but not open source. This is a significant advantage because the elements are linked to properties (among other things).Ī pre/post that supports NASTRAN (and MYSTRAN by extension). These are programs that can natively create a NASTRAN deck. However, not all preprocessors can create a compatible MYSTRAN deck (BDF/DAT). Preprocessors have the ability to create geometry, a mesh, apply loads, etc.

PreProcessors (With Native MYSTRAN Support) This is a pre/post that can create finite element models and can also read BDF files. This program no longer has a website, but the most recent version (1.1), can be downloaded here: It does not have post processing capabilities I found this to be a simple tool that is quite useful. It has a built in tutorial and low learning curve. It can be used to visually show the model, discover issues, measure, and perform various other operations. Many checks are also performed to verify that your model is correct.Ī lightweight program (only 3MB) that can read and interrogate BDF files. Using the BDF interface, you can read/edit/write Nastran geometry without worrying about field formatting. Additionally, you can also extract a subset of the result data and write OP2/F06 result files.Ī BDF (Bulk Data File) or DAT file reader can be read to interrogate models, but are not all programs can be used to create a mesh, apply loads, etc. Using the OP2 interface, you can read large result files quickly and efficiently. Instead, this thread will present low cost or free/open pre/post software that works with MYSTRAN. While there are commercial programs that can use MYSTRAN, such as MSC Patran and Femap, these programs are expensive and are usually combined with their own solvers.

MYSTRAN outputs OP2 and also NEU (though it is an older format). MYSTRAN is largely compatible with programs that can read BDF/DAT files.
