Objective:
You have digitized your geostring on sections, and want to use them for constrained modelling in VOXI.
Resolution:
There are several steps to this process:
- First wireframe your geostrings (connect them up in 3D space) to create a Geosurface. See Lesson 6.1 - Creating a Geostring File and Adding Features in the Oasis montaj Essentials On Demand Course.
- Then use this Geosurface to constrain a VOXI model to be, for example, your upper and/or lower bound constraints:
- If you haven't yet done so, you need to first create your and VOXI project and unconstrained model. You will want to create any constraint voxels with mesh dimensions as your model area. See the Unconstrained Inversion section of the VOXI Essentials Learning Paths.
- Create your voxel model to use as a constraint, such as for the upper bound: within VOXI: Constraints > Build a Model:
- Browse to your Unconstrained voxel as the Input Voxel
- Select Constraint type, such as Upper bound
- Browse to the Geosurface you saved earlier (select a Surface, if the Geosurface file contains more than one)
- Set up your value limits inside and outside your Geosurface
- This voxel can now be used as a constraint to impose value limits on your inversion model in VOXI: In VOXI Manager right-click on Constraint > Upper Bound > click Modify > select the constraint as Voxel and browse to select the saved created constraint voxel file.
