Tochnog Professional


This is an automatic input file generator for typical geotechnical problems. From basic geometry data it generates a complete input file, with all needed commands. In this way you don't need to find out yourself which commands are relevant. In the generated input file you need to adjust the values of parameters like material stiffness, plasticity data, etc. EasyTochnog works in combination with the GiD pre- and postprocessor (for making the FE mesh and visualisation); thus you also need to install GiD on your computer (see GiD pre- and postprocessor, the free GiD version can be used up to 10000 nodes). The generated input file should only be used on computers where EasyTochnog is licensed.

EasyTochnog comes at the price of 100 european Euro when it is computer locked, so each license works on 1 specific MS Windows or Linux computer only. The license will not work anymore if you change the hardware of your computer; you need to buy a new license. This is only available if you already have a node locked license for Tochnog Professional itself.

EasyTochnog comes at the price of 300 european Euro when it is dongle locked, and the license works on MS Windows or Linux computers in which the dongle is used. This is only available if you already have a dongle locked license for Tochnog Professional itself.

Use the EasyTochnog order form to order a license. This license includes all future updates of EasyTochnog. Please realise that the license is purely for the EasyTochnog input file generator. We will help you how to use this input file generator. However all further support needed for the generated input file and Tochnog Professional itself are NOT covered by the EasyTochnog license. You need to understand yourself the generated input file with the user's manual, and be able to change yourself the input file to your needs. If you, however, need further support see the Support page.
