I need to generate a 2d mesh of a topography that I have in different formats (*.asc, *.xyz, *.grd) and wanted to know if I can use the software for these purposes. The mesh will be used to simulate water runoff on a DEM (digital elevation model) with the Iber software (<a href="http://www.iberaula.es">http://www.iberaula.es</a>).</font></div><div class="gmail_default"><font face="arial, helvetica, sans-serif"><br></font></div><div class="gmail_default"><font face="arial, helvetica, sans-serif">If the program can incorporate the topography as input data, can it generate a mesh with irregular triangles with angles, maximum and minimum sides defined by the user? Can this mesh automatically refine in areas where there are sudden changes in topography? As an example I attach an image that I found on the internet that represents what I want to achieve with the mesh calculation.</font></div><div class="gmail_default"><font face="arial, helvetica, sans-serif"><br></font></div><div class="gmail_default"><font face="arial, helvetica, sans-serif">Thank you in advance for your response.</font></div><div class="gmail_default"><font face="arial, helvetica, sans-serif"><br></font></div><div class="gmail_default"><font face="arial, helvetica, sans-serif">Greetings from Chile.</font></div></div><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><i><div style="text-align:center"><font size="2" color="#000000" face="arial, helvetica, sans-serif"><i style="text-align:start"></i><div style="text-align:center"><i style="text-align:start"></i><div style="text-align:start"><font style="font-style:normal"><i style="text-align:start"></i></font><div dir="ltr"><font style="font-style:normal"><i style="text-align:start"></i></font><div dir="ltr"><font style="font-style:normal"><i style="text-align:start"></i></font><div dir="ltr"><font style="font-style:normal"><i style="text-align:start"></i></font><div dir="ltr"><i style="font-style:normal;text-align:start"><i><i><i><i></i></i></i></i></i><div style="text-align:left;font-style:normal"><div style="display:inline"><div style="text-align:center;display:inline"><div style="font-style:normal;text-align:start;display:inline"><div dir="ltr" style="display:inline"><div dir="ltr" style="display:inline"><div dir="ltr" style="display:inline"><div dir="ltr" style="display:inline"><i style="text-align:start"><i style="text-align:start"><i><i><i><i><div style="text-align:center;display:inline"><i><b><br></b></i></div></i></i></i></i></i></i></div></div></div></div></div></div></div></div><div style="font-style:normal;text-align:center"><i style="text-align:start"></i><div><i style="text-align:start"></i><font><i style="text-align:start"></i><div style="text-align:start"><i></i><div dir="ltr"><i></i><div dir="ltr"><i></i><div dir="ltr"><i></i><div dir="ltr"><i></i><div style="text-align:center"><i style="text-align:start"></i><div style="display:inline"><i style="text-align:start"></i><div style="display:inline"><i style="text-align:start"></i><div style="text-align:start;display:inline"><i></i><div dir="ltr" style="display:inline"><i></i><div dir="ltr" style="display:inline"><i></i><div dir="ltr" style="display:inline"><i></i><div dir="ltr" style="display:inline"><i><i><i><i><i><i><i><div style="text-align:center;display:inline"><i><b><div style="display:inline"></div>Boris Zúñiga Lucero</b></i></div></i></i></i></i></i></i></i></div></div></div></div></div></div></div></div></div></div></div></div></div></font></div></div></div></div></div></div></div></div></font></div></i></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div>
