i-ROM FEM core

Finetuniung with FEM (06/23/2023)

What lasts long becomes good. We have reached our goal. Our own FEM tool!

The fastest and most accurate FEM program for MEMS design you have ever seen, because it is tailored to the specific needs of MEMS design.

If you need

  • case-specific meshes for perforated solids and comb cells,
  • 3D FEM models with etch sidewall slops and corner fillets at spring junctions,
  • displacement dependent capacitance functions or
  • viscous damping for characteristic eigenmodes of vibration

then the i-ROM FEM core is exactly what you need.

If you want to simulate and optimize the behavior of your micromechanical sensors and actuators in the shortest possible time and with high accuracy, then contact us.

i-ROM Sketcher

MEMS design is complex - we make it intuitiv (01/01/2022)

It doesn't work without a drawing program. Even if we actually come from the analytical world, that was a matter of course for us. So it was our goal to make a really intuitive sketcher. Now our sketcher is ready to use. And it makes the your MEMS design really easy. Anyone can use our sketcher, even without extensive training. With us you no longer have to be a MEMS expert with many years of experience to design professionally. Just try it.

i-ROM Modelbuilder Cloud

When flexibility is required (06/21/2021)

We are now also offering you the model maker as a software-as-a-service package for use. All you need is an internet-enabled computer. We'll do the rest. No installation, no administration, just log in and off you go. Billing is per user and month.


Designing advanced sensors is not coincidence but the result of a systematic approach (12/20/2020)

The i-ROM MODELBUILDER is the first simulation tool that considers changing design parameters, manufacturing tolerances and user requirements in no time and simulates the interactions of the various influencing factors. The results are available just seconds later for further optimization of your design and thus shorten the time-consuming design process many times over.

Interfaces to MATLAB SIMULINK and ANSYS are available for fine tuning, so that the MODELBUILDER can be easily integrated into your software structure.

Getting started is easier than you think. The professional USER MANUAL guides you step by step and explains in detail using examples of how acceleration sensors, angular rate sensors and micromirrors are designed.

Target groups are engineers who design sensors and actuators for consumer products and for the automotive industry. In academia, the i-ROM MODELBUILDER supports lecturers to train students with realistic examples and make classroom theory come alive.

Test the i-ROM MODELBUILDER for free. We are available for your first steps at any time. Of course, preferred online and free of charge. We are looking forward to your message.

We are here for you
