Our wide range of engineering experience and knowledge of numerical methods gained over 20 years have given us the advantage in developing process improvement software solutions. Many companies are unaware what is possible when unconstrained by commercial software. A bespoke software solution that fits a particular process needs can radically improve productivity and dramatically reduce cost/
Some examples of what we've done
Example: Astrium's QWANTA program
An example of such an application written for Astrium automatically generates Finite Element models from a Catia assembly. This program has reduced their modelling time from weeks to hours. When a new solid model assembly is generated in Catia a text file defining the parts name and location is generated. From this file M3d automatically positions the component parts from a Finite Element mesh library and connects them together with swept tubes as shown. The Finite Element model shown was generated in under 30 seconds
This program uses our own M3d modelling engine which is easily customizsed into such applications

Example: Software for Rolls Royce
First pass axi-symetric combustion chamber Finite Element modeller, Finite Element solver and post-processor developed for Rolls Royce. (This has reduced the time for one design iteration from days to minutes and this means a much more optimised design).
This is a 2d Finite Element modeller/solver and post-processor written and contained entirely within an Excel workbook. The executable code is written in VBA.

Models are generated by specifying the sections and interconnecting flanges in the modelling dialog box. Each added section is displayed on the viewing window as it's created allowing visual model verification. The section can be edited at at any time. On solution, the Finite Element model is generated automatically and the system equations solved.
Plots of stresses and displacements are generated automatically as illustrated right. Results compare with MSC Nastran.

Over the last 12 years we have been developing applications for the aerospace industry using the Femap API. The Femap API provides an excellent platform for developing bespoke automated methods to greatly reduce man hours used on repetitive tasks.
Traditionally critical locations and load cases were selected subjectively, the new methods developed have enabled the whole analysis space to be calculated in a fraction of the time. Examples of some of the applications include:-
Data extraction, transformation, formatting and summary reporting;

Data extraction, transformation, formatting and summary reporting;
- Results visualization;
- Composite methods;
- Failure indices calculation and contour plot generation;
- Bearing bypass calculations - every bolt - every load case;
- Face skin instability - every element - every load case;
- Core shear;
- Parametric model generation and
- Pressure mapping
Example: Radial stress visualisation of the stresses around a bolt loaded hole
Example: Parametric model generation
The model shown right represents a generic fitting on a wing spar of which there are many. Each of the fittings have different bolting configurations, material thicknesses and loading configurations.
The Finite Element model was generated automatically from a parameter listing in Excel. Loading and boundary conditions were applied and the load cases solved in NX Nastran automatically. The results were retrieved, combined and reported to an Excel workbook

We cannot stress enough how powerful the Femap API is and how it can revolutionise the way you do analysis. The cost savings from having a cleverly thought out process using a bespoke application at the beginning of a project can be immense.
