Pest and Disease - Calling a variable from a sim and hold it constant #8163

Closed jambon17 closed 11 months ago

What is your question?

Context:

  1. The growth rate of the pathogen within the plant (from the leaves to the stem base) is calculated as [1/Target Thermal Time]*MeanTemp.
  2. Target Thermal Time (Target TT) is defined by the leaf or node number (i.e., leaf crop growth stage when the plant was infected) via linear interpolation in the model.
  3. The model calls the Target TT value when the lifecycle stage has been initiated.

The aim was to hold the Target TT value of the specific crop growth stage when the lifecycle stage has been initiated to predict when the pathogen reaches the stem base. However, the Target TT value changes every day due to the changing node number as the crop develops. Is there a way I could have that value constant for the pathogen development?

In the example below, I wanted to use the value 980.067 under the TargetTT_GS column. So when the thermal time has reached this value, I can move on to the next lifecycle stage...

Any suggestions are appreciated!
