 Otherwise, in the current implementation, we waste memory and CPU time by doing viscoelastic simulations everywhere, even in elastic regions, when TURN_ATTENUATION_ON is on.
 
+More precise analysis from Dimitri: 
+this means in particular changing this in DATA/Par_file:
+
+ATTENUATION_VISCOELASTIC_SOLID  = .false.        # turn attenuation (viscoelasticity) on or off for non-poroelastic solid parts of the model
+ATTENUATION_PORO_FLUID_PART     = .false.        # turn viscous attenuation on or off for the fluid part of poroelastic parts of the model
+
+and making it local to each material set instead of global for the whole mesh.
+
 Feedback from Qinya: I agree. The way attenuation appears in the 2D Par_file is quite confusing. It will be good to clean up, or at least explain well in the manual.
