2017: Next User Training / Nächste Schulung

Dear Telemac users, customers, colleagues and friends,   Due to the still growing response to the Entry Level Courses we proceed in the 5 th year of user trainings. Even though the first trainings at the Flanders Hydraulic Laboratories and at the Laboratorio National in Lima are finished without ever being announced, we still have 3 ...

Telemac-AD

- Einführung (German)  Telemac-AD kann den Einfluss räumlicher Störgrößen auf Strömungen punktgenau rückrechnen. Diese in der Gewässermodellierung revolutionäre Technik ermöglicht die Lösung bisher physikalisch und numerisch kaum modellierbarer Fragestellungen, weil der Einfluss pro Knoten und Parameter ohne Überlagerung mit anderen quantifiziert wird. In der Fließgewässerhydraulik kann dieses Verfahren zur automatischen Optimierung und Kalibrierung strömungsrelevanter Formen, zur Data ...

Telemac-AD Adjoint Example 4: Piers and Eddies

More detailed Description: Telemac Users Club 2016: 20161018-tuc2016_kessler_merkel.pdf Question:   Vertexes / Eddies / Flow fields induced by obstacles  (e.g. salinity or temperature): How does the shape (x,y,z coordinates) affect the field of flow, here: development of Karman Vortex Streets? Difficulty: Inverse Problem: As potentially any points bathymetry value X, Y, Z in the model affects ...

Telemac-AD Adjoint Example 1: Shear Stress in a Groyne Head Scour

Question: How is the erosive shear stress τ at a certain point influenced by the neighboring bed geometries or the neighboring bed roughness? Difficulty: Inverse Problem! As potentially any point in the model affects the shear stress even over longer distances due to its ability to alter the water level with its properties ZF=Bottom Elevation or KS=Equivalent Sand ...

Telemac-AD Adjoint Example 2: Detecting Reasons for “Low Free-board” and “Local Velocity Extrema”

Question: This inner city river channel has to maintain many different boundary conditions to be used as a Kayak Slalom Parcour The free-board to maintain flood safety The maximum velocity, to reduce erosive forces and to not hinter fauna migration The bathymetry (especially the obstacles) are given by the designing landscape architects and shall not be removed, but ...

Telemac-AD Adjoint Example 3: Shape optimization of bathymetry for a better distribution of a Tracer

Question: Mixing of a Tracer (e.g. salinity or temperature): How does the shape (x,y,z coordinates) affect the mixing of a tracer? Difficulty: Inverse Problem: As potentially any points bathymetry value X, Y, Z in the model affect one mixing indicator. Experimental Setup: This is an academic example to show the usage of adjoints for tracer mixing ...
