The interface between MDESIGN and the ANSYS plug-in FAST+MORE for the calculation of fasteners is now available. This makes it possible to efficiently analyze designs with often hundreds of bolts with FEM and to perform a detailed verification according to VDI 2230 or Eurocode 3 in MDESIGN.

FAST+MORE is an ANSYS extension developed by 7tech GmbH that can be installed quickly and easily via the ACT console. It is fully integrated into the ANSYS interface and therefore requires no extra learning effort, the workflow is perfectly tailored to large models. FAST+MORE automatically recognizes the correct bolt dimension based on the existing holes and, depending on the user's requirements, models the bolts either as model class I (direct coupling of the holes without a bolt model), model class II (bolt as a beam model) or model class III (bolt as a solid model). Bolt preload and tightening torque, including various tightening methods, are provided from a database.

FAST+MORE can display the results graphically on the model as well as generate tables. This allows you to quickly find the bolt with the lowest safety factor. In addition, a detailed report with all input and result variables can be displayed for any bolt .

The results of bolt are exported to MDESIGN at the click of a mouse. This often saves the time-consuming and error-prone manual transfer of internal forces and bolt data. In MDESIGN, you benefit from the other outstanding options for reliable verification calculations in accordance with VDI 2230 or Eurocode 3. The automatic creation of documentation - also multilingual - not only saves time, but also ensures that the required project times are adhered to.
