+# Short Description
+
+This dataset comprises solutions of the Helmholtz equation.
+
+# Dimensions
+
+The H5 file has **19675** variables called *Sample_i* where i is the sample number. Every sample has three sub-groups:
+*a* with dimensionality
+  - 128 (x-dim)
+  - 128 (y-dim)
+*bc* (the value of the Dirichlet boundary condition, a float), as well as *u* with dimensionality
+  - 128 (x-dim)
+  - 128 (y-dim)
+
+# Train/Val/Test-split
+
+19035/128/512 trajectories
+
+# Download
+
+The dataset can be downloaded, e.g., via `huggingface-cli download`.
