PLUGIN Functionality in iMOD WORK PROCESS

Usage of Mock-UPS-sessions:

Sketch and design the look-and-

feel, interactively

The functionalities and

limitations

Plugin need to:

Easy to implement;

Exchange some basic

information from and to iMOD;

Support some basis interaction

with users via dialogs

1)

Add Keyword

PLUGIN1 or

PLUGIN2 in

*.PRF

3)

Activate existing Plugins so that

they become available in iMOD

and can be executed

Plugin that operates in the

background can generate

output or messages to be

picked up by iMOD

4)

Interaction to select files from the

iMOD Manager to be transferred to

the Plugin

Python script based

program as alternative to

perform more complicated

math than with IDF-Edit

IPS – Interactive Particle Simulation CONCEPT

Performance of the model – easy to observe “strange” behavior or

undesired connection between aquifers;

Increase stakeholder participation and -involvement by making the

movement of groundwater flow visible;

Ability to illustrate flow behavior,

velocity and direction of

groundwater in an interactive

manner to gain insight of:

IPS – Interactive Particle Simulation CONCLUDING REMARK

IPS can be applied to a part of the model by zooming in before

starting the IPS to increase performance;

IPS can be started with a “user-defined-display” creates the

possibility to include boreholes or alternative sources of 3D

display during the particle tracking;

Particles can be save for future analyses;

Further improve IPS to further increase the experience of how the

3-D flow groundwater patterns behave and develop – thinking of:

Traveling along a streamline; and

Interactively interact with the velocity field to observe changes

in flow-pattern due to measures: what-if scenarios.
