New file metadata dialog

Published at: 2024-10-18

A long-standing request is to save "notes" or some additional user information with the files. This can prevent the current practice of putting all simulation parmaters, etc. in the filename.

Python interface for MolFlow files

Published at: 2024-09-26

Many advanced users of MolFlow post-process, or even modify the saved geometries. Until now, they had to understand the file format and write an XML parser/writer. This new interface makes this advanced use case easier.

Measuring molecular forces with MolFlow+

Published at: 2022-12-05

As part of collaboration with space industry players, we got a feature request to calculate the force and the torque exerted by molecular hits on either individual facets or on an object that consists of multiple facets. This is now implemented in the...

Convergence plotter

Published at: 2020-11-05

Following another user request and the wish to compare different configurations more easily, we created a new analysis tool, the Convergence plotter. As it is deeply entangled with the Formula Editor, you can open it directly from there (or via the...

Generating accelerator sequences with OpticsBuilder

Published at: 2020-09-08

3D modeling in CAD programs requires a steep learning curve and expensive software. Using Molflow's built-in editor to create a sequence of apertures and connect them manually is tiresome. A helper tool, OpticsBuilder can automate the process - it...

Geometry editing options

Published at: 2017-10-12

Originally, Molflow+ was intended to be used as a simulator, not a CAD editor - the source of the geometry always had to be an STL file. Over the years, editing options were added to perform quick fixes on the geometry - such as plugging holes,...
