Yes, you can use the magnetic problem for velocity model, and set magnetic starting model to your velocity model. To achieve this use the following Parfile parameters:
inversion.startingModeling.type=2 inversion.startingModeling.magn.file= Your velocity model inversion.startingModeling.grav.file= Model with zeros
Also use the following setting for the cross gradient constraint: inversion.crossGradient.magn.keepModelConstant = 1
And set the low problem weight for the mag problem (to ignore its data term): inversion.joint.grav.problemWeight = 1.d0 inversion.joint.magn.problemWeight = 1.d-30
Thanks for your reply!I will try it.
Hi, Thanks for sharing the code! I'm tring to add structual similarity constaints into gravity anomaly inversion using velocity model, however, the program seem to only support cross-gradient inversion between grav and magnetic data. I'd like to konw if Tomofast support cross-gradient inversion using other type of geophysics model?
