A grid (mesh) defines a tessellated collection of small volumes that cover the 3D volume of space that is to be simulated using CFD. The governing equations are integrated (discretized) over these volumes and solved iteratively until they those equations are satisfied. Out of the process comes predicted values of temperature, pressure, velocity etc. at each of those grid cells. … [Read more...]

Software can be described in two ways, what it does (functional) and how it does it (non-functional). As a software matures in terms of its functional capability it is often the case that more effort goes in to developing it's non-functional strengths. We introduced 'FloSCRIPT' with V10, a scripting language to enable FloTHERM to be operated without the need for laborious … [Read more...]

With FloTHERM V10 we embarked on a GUI replacement program to update the GUI and user experience for all of FloTHERM's application windows. In V11 the replacement program continues with FloMCAD. As with all such evolutionary approaches it is important to maintain the paradigms on which the software is based so as not to necessitate retraining but also provide an improved more … [Read more...]

The simulation of MCAD geometry is a day to day requirement for the majority of thermal design engineers, especially those at systems integrating companies. Despite repeated advances over the last 2 decades in the robustness of neutral format readers and writers, feature recognition functions and healing algorithms, importing and preparing MCAD data for analysis is still not a … [Read more...]

FloTHERM V11 is now released and contains a wealth of interesting and useful features. In this blog series I'll select my favourite top 7 and explain each one in some detail. To start with, Joule heating, also know as resistive or Ohmic heating. Joule heating is the power lost to heat as electrical current flows down a conductor. I^2R, VI, we were all first introduced to this … [Read more...]
