The last version 5.

4 includes two new products provides performance improvements and additional modeling tools.

Version 5.4.0.388 – Date: June 4, 2019All COMSOL software products undergo stability improvements that are introduced as updates.

The following list contains the most important improvements in COMSOL version 5.

4 update 3.

COMSOL Multiphysics– External materials no longer trigger multiple license key checkouts.

– Increased the robustness of COMSOL Client over WAN connections.

– Fixed a potential deadlock when connecting to a server using the COMSOL API or LiveLink for MATLAB.

– The page layout settings (such as page size, margins, orientation, and columns) of a specified custom Microsoft Word template file are now used when writing reports in Microsoft Word format.

– Fixed a bug that prevented writing a report from method code to a file specified in a file browser dialog box when using the default security settings.

– Fixed a problem where the MUMPS solver might crash or hang during cluster simulations.

COMSOL Server– Fixed a layout issue with the COMSOL Server footer in Chrome 72+.

Composite Materials Module– Fixed an issue in the Layered Shell interface, where the total thickness (lshell.

d) would be erroneously computed if the layers on a certain boundary were not all selected in the same Linear Elastic Material node.

Heat Transfer Module– Removed erroneous mesh suggestions generated by the Continuity feature for shells.

MEMS Module– Corrected the equation display for the Heaviside step function.

Particle Tracing Module– Fixed some inconsistency in the assignment of units for the Auxiliary Dependent Variable feature.

– The variable for “Total number of particles released by feature” now gives the correct solution in models that also have secondary particle emission.

– Two or more instances of Magnetophoretic Force are now allowed to be applied to different species in the same model.

Structural Mechanics Module– Corrected an error occurring when the values of the total reaction force variables were wrong if a load was applied on a Rigid Connector in which the soft formulation had been selected.

– Corrected an error occurring when the Activation feature was combined with geometric nonlinearity in a 2D axisymmetric model.
