LIMS 5.0.8. Demo

Download the Windows version of LIMS restricted to 3000 nodes mesh. Note that this release times out as all others (on July 31st 2026).

NOTE: The program install folder defaults to C:\lhome. Change it as you will but DO NOT install into folder containing spaces in path, as the GUI will not find its simulation engine. Most of all, avoid “Program Files” as the access controls on this folder will also prevent you from running examples or editing scripts in default folder.

Assignment 2 contains LIMS and LEGO files for simulation of a simple linear injection experiment. The “sample” files are just a quad, but “complete” shows the problem definition with racetracking channels and inlet tubing as well as how to work with “zone” files from lego.

Additional LIMS Tools and Samples

A great number of tools were created for LIMS over time, by the LIMS team, other users or students. Some are available. These are described below. If they are made available, there will be download link there. Note that they are without any warranty whatsoever. Utilities are generally developed to accomplish some simple task and shelved when this is accomplished, regardless of existing issues. If you need something that is mentioned below and not available as a download link, and you are willing to take the risk, feel free to contact us.

Lego

Lego is a simple script-driven mesh. It proved useful to build simple models, but also to deal with cross-section models that are hard to create in other tools because of extreme geometrical aspect ratios and proper element orientation the cross-section model needs. Lego is bundled in LIMS, but there is a newer version available. I will add it to next install, otherwise, it can be downloaded here (zipped binary and .chm help file).

 Shell2Solid

This command line utility converts 2.5D shell LIMS mesh into a 3D solid by extruding shell into given half-space according to element thickness in 2D mesh. This mesh may have very thin element as needed to model highly anisotropic through-the-thickness flow. It allows one to selectively extrude only a certain zone (region) in the mesh and keep the rest as it is or keep the original 2D elements. Number of layers and through-the-thickness permeability may be specified. There is “reverse” utility solid2shell. Contact us if you need this.

 Remdupel

This command line utility allows one to “fix” improperly generated mesh by merging duplicate nodes at the same (or close) coordinates and consolidating multiple elements between same nodes into one. LimsUI can do this job as well (same code) but it uses preset values. The command line utility allows better adjustment. This is just a simple set of .cpp and .h files that you will need to compile (works cross-platform).

Remorph

This command line utility allows one to “fix” improperly generated mesh by deleting nodes not connected to any elements. These might be left from the construction geometry. Again, LimsUI can do this job as well (same code) but it uses preset values. This is just a simple set of .cpp and .h files that you will need to compile (works cross-platform).

File Converters

There are several converters available to convert the certain file formats into LIMS input (.dmp). What is converted and what fails varies. These tend to be more complex in their usage as they need to handle material parameters. If you need just the node-element system and plan to set permeability in LimsUI, process any geometry you have through GMSH, save it as ASCII V2 mesh and follow the tutorial.

• I-deas .NEU is built in LimsUI. It is 2D only. Command line version exists. There is also AWK script for simple files
• Abaqus .INP is built in LimsUI. Again, there is even older command line version
• Patran .IN format for 2D shells command line version exists
• .BDF format is (unlike the ones above) being actively developed, but it is far from complete. It concentrates more on 2.5D shells and it can use laminate layups and FibersimTM output. There is also simpler AWK script for this conversion which should be easy to modify.
• GMSH .MSH format (ASCII V2) is read directly into the command line. Command line tool has been developed which adds support for physical domains and generates proper LIMS region files.
