About us

Our company performs computational simulations and provides professional counseling and support in the area of design, dimensioning and optimization of machine parts, whole structures and complex engineering assemblies in many industries. Our team consists of experts with extensive experience in the domain of computational fluid dynamics – CFD, finite element analysis of structures – FEA and electromagnetic simulations – EM. All analyses are carried out using the worldwide well-established computational software. The company capitalizes on years of computing experience in fast-growing areas of electro mobility and sustainable energy. We are offering cooperation in the framework of individual custom computations, research and development projects and professional counseling and support.The company has a number of excellent references in the automotive industry, traffic engineering, power engineering and turbo machinery. It’s customers include companies such as DOOSAN SKODA Power, HOWDEN Compressors, PBS ENERGO, SIEMENS Industrial Turbines, SKODA Auto, SKODA Electric and many others.

In 2016 the TechSim Engineering company expanded its activities into the sale of simulation software after becoming the SIEMENS Solution Partner with full exclusivity for the programme product SimcenterLMS Imagine.Lab, NX Nastran, LMS Virtual.Lab  LMS Samtech and others.
