Deltares has released Wanda version 4.2.1. This version is a bugfix release with minor improvements.
This release includes the following fixes and improvements:

  • Improvements to logging facilities, preventing problems in IT environments with security restrictions
  • Resolved an issue where the VENT component (airvalve) would become stuck in an incorrect state under some circumstances.
  • Resolved an issue where Wanda could not read input files due to long paths + filenames
  • Resolved an issue where the inclined airvessel discharge would round down to 0 for low discharges.

New functionality
Added the 'Liquid node with conditional head'. This node allows you to specify the head (similar to the Hnode with initial head), but only when necessary.
When a part of the system is isolated during the steady state computation, the head in that part of the system is not determined by the system. The user can use the H-node with initial Head to solve this problem. However, when using the parameter script, the user cannot switch between certain types of nodes. This node allows the system to specify the head at it's location, but uses a user-specified head when the system can't do this.
