With a feature set that surpasses many commercial FEM programs, Code_Aster is particularly well-suited for complex structural, thermal, and coupled analyses in industrial and scientific environments.<\/p>\n\n\n\n<p>We have more than <strong>10 years of practical experience<\/strong> in the professional use of Code_Aster and use this FEM code for a wide spectrum of demanding calculation tasks \u2013 from simple static analysis to highly complex transient simulations with nonlinear material behavior and contact.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Our services with Code_Aster at a glance<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Static and transient structural analyses<\/h3>\n\n\n\n<p>Whether it's operating load, impact, or time-varying loads \u2013 we calculate the mechanical behavior of components and structures under realistic load conditions. We utilize the full range of element types offered by Code_Aster:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Volume elements<\/strong> \u2013 for massive components, welds, and complex 3D geometries with detailed stress analysis<\/li>\n\n\n\n<li><strong>Shell elements<\/strong> \u2013 for thin-walled structures like sheet metal, containers, pipelines, and housings with high computational efficiency<\/li>\n\n\n\n<li><strong>Stab and beam elements<\/strong> \u2013 for frame structures, steel structures, and system models with many degrees of freedom<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Contact problems and nonlinear analyses<\/h3>\n\n\n\n<p>Contact problems are among the numerically most challenging tasks in FEM. Code_Aster offers robust algorithms for this purpose, which we specifically employ for issues such as press fits, bonded joints, sealing surfaces, or the lifting of components under operational loads. Geometric and physical nonlinearities \u2013 such as large deformations or elastoplastic material behavior \u2013 are also accurately represented.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Screwed connections<\/h3>\n\n\n\n<p>The realistic modeling of bolted connections in FEM models requires both methodological know-how and experience with the peculiarities of the respective solver. We simulate pretension forces and the elastic behavior of bolted connections using proven methods \u2013 for reliable validations according to common standards such as VDI 2230.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Eigenfrequency analysis and modal analysis<\/h3>\n\n\n\n<p>Knowledge of the natural frequencies and mode shapes of a structure is a prerequisite for assessing resonance risks and designing vibration-damped constructions. With Code_Aster, we perform modal analyses and, if necessary, combine them with harmonic or transient vibration response calculations \u2013 for example, for rotating machinery, piping systems, or seismically stressed installations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Code_Aster \u2013 and why with us?<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>No licensing cost overhead<\/strong> Code_Aster is open source under the GPL license and enables cost-effective calculations even with high computational volumes or parallel projects.<\/li>\n\n\n\n<li><strong>High solver quality<\/strong> The code has been used and validated by EDF for safety-critical applications in nuclear engineering and power supply for over 30 years.<\/li>\n\n\n\n<li><strong>Reproducible, documented results<\/strong> \u2013 all simulations are built in a traceable manner and completed with engineering evaluation of the results<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Typical Industries and Application Areas<\/h2>\n\n\n\n<p>Our Code_Aster projects span numerous industrial and engineering fields:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mechanical and plant engineering \u2013 stress analysis for pressure vessels, flanges, welded constructions<\/li>\n\n\n\n<li>Energy and Process Engineering \u2013 Piping Analyses, Heat Exchangers, Vessel Design<\/li>\n\n\n\n<li>Vehicle and Rail Vehicle Technology \u2013 Crash-Relevant Structures, Durability Proofs<\/li>\n\n\n\n<li>Aerospace \u2013 Lightweight structures with fiber composite materials and adhesive bonding<\/li>\n\n\n\n<li>Construction and Infrastructure \u2013 Seismic Analysis, Steel Construction, Foundation Verification<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Requesting FEM calculation with Code_Aster<\/h2>\n\n\n\n<p>Are you looking for an experienced partner for structural mechanics calculations with Code_Aster? <strong><a href=\"https:\/\/silentdynamics.de\/en\/kontakt\/\" data-type=\"page\" data-id=\"396\">Contact us<\/a><\/strong> \u2013 we will discuss your task and jointly develop an efficient and robust simulation strategy.<\/p>","protected":false},"excerpt":{"rendered":"<p>Code_Aster ist einer der leistungsf\u00e4higsten und zugleich anspruchsvollsten Open-Source-Finite-Elemente-Codes weltweit \u2013 entwickelt und kontinuierlich gepflegt vom franz\u00f6sischen Energiekonzern EDF.
