(Original )Information
What do you like best about Gmsh?

How powerful the software is and that it just *works*. Fixed many issues for me in my FE modeling projects. Review collected by and hosted on G2.com.

What do you dislike about Gmsh?

Nomenclature is non-standard and unintuitive at times. Menu style is very unusual, simple tools and features are buried in places they don't belong. Review collected by and hosted on G2.com.

What problems is Gmsh solving and how is that benefiting you?

Complex meshes driven by real-world data, especially through noisier imaging modalities, often have errors and overlapping geometry. Gmsh can help fix that. Review collected by and hosted on G2.com.

Gmsh Overview

Editedit
What is Gmsh?

Gmsh is a free 3D finite element mesh generator with a built-in CAD engine and post-processor. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities. Gmsh is built around four modules: geometry, mesh, solver and post-processing. The specification of any input to these modules is done either interactively using the graphical user interface, in ASCII text files using Gmsh's own scripting language (.geo files), or using the C++, Python or C API.

What do you like best about Gmsh?

The best part of Gmsh is that it's open-soruce. Meshers are generally expensive and complex so the open-sourceness is it's main advantage. Secondly, despite being open source, it's pretty powerful! It allows you to make structured and unstructured meshes and import complex geometries from other softwares. Review collected by and hosted on G2.com.

What do you dislike about Gmsh?

Most of the complex options aren't available through the GUI, so scripting is required. Also the GUI sometimes mess up with the backend script, so the scripting part is pretty much mandatory. Finally, there scripting is not intuitive at all, and the documentation is weak. Review collected by and hosted on G2.com.

Recommendations to others considering Gmsh:

Start with the scripting. The GUI is intended to ease the scripting, not to replace it. Review collected by and hosted on G2.com.

What problems is Gmsh solving and how is that benefiting you?

I work in computational biomechanics of the heart so I mesh hearts, ventricles atrias and related biomedical devices. Review collected by and hosted on G2.com.
