Although PALM will not abort due to this warning, the chosen grid setup might lead to untrustworthy results. The reason for this is an unfavourable choise of grid anisotropy. To avoid this, make sure that the values of [../inipar#dx dx], [../inipar#dy dy], and [../inipar#dz dz] do not differ too much from each other. In case of grid stretching, the settings of [../inipar#dz_stretch_level dz_stretch_level] and/or [../inipar#dz_stretch_factor dz_stretch_factor] should be changed to ensure a smaller difference between {{{dz(k)}}} and {{{dx}}} and {{{dy}}} at the reported height level. ||
