If you want to make a change to your current license, please post your request below. Typical changes are upgrades from YASARA Model to Dynamics, from academic to commercial usage, or from a single to a group leader license. If you want to change from YASARA View to Model or Dynamics, please use the order forms instead.
If you are not sure about the cost of the upgrade, use the License Fee Calculator . Your YASARA account will be charged with the difference between this price and the current value of your existing YASARA license. Feel free to request more details using the form below.
