Dalík et al. and it is briefly explained and numerically tested in this contribution. Nodal value of P1 gradient is computed by averaging of P0 gradients on elements sharing the node in a common patch. cav_un_auth*0316850 INTERNATIONAL CONFERENCE ON NUMERICAL ANALYSIS AND APPLIED MATHEMATICS 2014 (ICNAAM-2014) 22.09.2014-28.09.2014 Rhodos GR BA 10000 10100 10101 2016 PR RVO:67985556 http://hdl.handle.net/11104/0246681 1 cav_un_auth*0316851 Fakulta informačních technologií VUT Brno VUT FIT Brno CZ S RIV/67985556:_____/15:00444085!RIV16-AV0-67985556 191684232 Doplnění UT WOS a oprava názvu RIV/67985556:_____/15:00444085!RIV16-GA0-67985556 191719389 Doplnění UT WOS a oprava názvu 0.160 Q4 2015 84939649022 SCOPUS 000355339705132 WOS cav_un_epca*0444084 PROCEEDINGS OF THE INTERNATIONAL CONFERENCE ON NUMERICAL ANALYSIS AND APPLIED MATHEMATICS 2014 (ICNAAM-2014) 978-0-7354-1287-3 0094-243X 850080-1-850080-4 Rhodos AIP 2015 AIP Conference Proceedings 1648
