About Online FEA Solver
I am an independent FEA consultant using the open source Calculix FE
code. The services I offer are:
- General FEA structural analysis consulting on linear and non-linear problems
- Topology optimization, i.e load path analysis to determine optimal placement of
material in your designs to save weight
- Online compute service to let analysts run their large FE models on my servers.
Uploaded input decks need to be in the Abaqus input deck format
- Software development to automate post-processing of
your FEA results data for specialized applications
For consulting, I focus on the most common analysis
types, i.e linear static, material plasticity, geometric non-linearity and
contact. The history of FEA has shown that these analysis are generally
all that is needed to understand 95% of most mechanical phenomena. In any
case one should always begin an FEA analysis with simplicity and add
complexity as needed. Therefore you can use my services to push more of
your routine analysis upfront and thereby reduce the number of licenses
you have to purchase for expensive commercial FEA solvers.
My topology optimization service provides you with videos of
how material is distributed in
your structure. You can watch some sample videos here. I wrote the entire script myself based
on an evolutionary algorithm.
For the compute cluster , I provide full technical assistance to ensure your models will run and converge. Your
input decks needs to be in the Abaqus format. Abaqus is the de facto standard for finite element input decks and most
pre-processors are able to export an Abaqus input deck. I will communicate any issues I find and provide technical
recommendations for how to resolve the issues. Futhurmore, I will
leverage my experience with non-linear analysis to make sure your jobs
converge quickly and provide meaningful results.
Please note that results obtained from CalculiX are in no way connected to Abaqus, which is a
proprietary, general purpose finite element code developed and supported by Dassault Systemes.
I also can write software to automate the labor intensive tasks of
post-processing your result data. Many analysts use Microsoft Excel to do
their own calculations on results file. This can be quite time consuming
and error prone . I would be glad to develop scripts written in either
Python or Perl to automate your process. I can also develop web-based
calculators and softwares as in my beam bending stress examples.
I am still in the pilot phase and am actively looking for analysts to
try my services at no cost or obligation.
