Hello Luis, Maybe it is a coordinate reference system problem? It looks like you're using wgs84 for the input and coordinates, and requesting the calculation in meters (obs_elev, tgt_elev and max_dist). Try to change the CRS to see if it works.
r.viewshed -b input=Portada@inisig output=visPort *coordinates=-3.74034324324,42.5352702703* obs_elev=9 tgt_elev=1.75 max_dist=30000 Computing events... Computing visibility... r.viewshed: statusstructure.cpp:73: float get_vertical_angle(Viewpoint, StatusNode, surface_type, int): La declaraci?n `*fabs(sn.dist2vp) > 0.001*' no se cumple.
