## Retaining wall analysis – FEA and hand calculations

I have used the PlateMC spreadsheet described in the previous post to compare the results of a finite element analysis of a retaining wall with a similar analysis using the commercial package Strand7, and a simple hand calculation using Coulomb … Continue reading

## FEA slope analysis; effect of mesh size

The last version of the FEA slope analysis spreadsheet (presented here) allows the slope shape and element density to be easily varied. This post looks at the effect of varying the density from very coarse to fine, with constant soil … Continue reading

## Linking Excel to Fortran with ctypes; update

In the previous post arrays were created in Python and passed to a Fortran dll as ctype pointers. The data written to these arrays in the Fortran routines was then converted back to Python arrays with statements such as: nodedisp = npc.as_array(nodedisp). … Continue reading

## Linking Excel to Fortran, via xlwings, Python and ctypes

Continuing the recent series on using Fortran code published in Programming the Finite Element Method (5th ed. John Wiley & Sons, I.M. Smith, D.V. Griffiths and L. Margetts (2014)), this post looks at linking Excel to Fortran code compiled as … Continue reading

## Compiling Fortran code for Windows

This post is a continuation of a recent series, using Fortran code published in Programming the Finite Element Method (5th ed. John Wiley & Sons, I.M. Smith, D.V. Griffiths and L. Margetts (2014)). The compiled file provided in the download should … Continue reading

## Running exe files from Excel

Following on from the previous post (running a compiled Fortran finite element analysis program from Excel), this post looks at the details of calling any command line routine from Excel, through VBA. The important points that need to be addressed are: Writing … Continue reading
