From 26d16d7b039959a4477e036d16c6919bd8abc70d Mon Sep 17 00:00:00 2001 From: Frederik Schnack Date: Mon, 28 Sep 2026 13:44:12 +0200 Subject: [PATCH 01/22] Remove obsolete legacy test artifacts Delete the unmaintained old/ snapshots and bin/run_tests.sh. The script references test modules that no longer exist, so it advertises a broken workflow while the deleted snapshots duplicate history already preserved by Git. --- bin/run_tests.sh | 18 - old/form.py | 2210 -------------------------------------- old/test_calculus.py.old | 161 --- old/test_expr_1d.py.old | 429 -------- old/test_expr_2d.py | 471 -------- old/test_expr_3d.py.old | 589 ---------- old/test_form_2d.py | 1487 ------------------------- old/test_form_3d.py | 110 -- old/test_tensorize_2d.py | 136 --- 9 files changed, 5611 deletions(-) delete mode 100755 bin/run_tests.sh delete mode 100644 old/form.py delete mode 100644 old/test_calculus.py.old delete mode 100644 old/test_expr_1d.py.old delete mode 100644 old/test_expr_2d.py delete mode 100644 old/test_expr_3d.py.old delete mode 100644 old/test_form_2d.py delete mode 100644 old/test_form_3d.py delete mode 100644 old/test_tensorize_2d.py diff --git a/bin/run_tests.sh b/bin/run_tests.sh deleted file mode 100755 index da2ed3e0..00000000 --- a/bin/run_tests.sh +++ /dev/null @@ -1,18 +0,0 @@ -#!/bin/bash -

From 1c37b9b11e3aff3321cf139227b8ea376a1beebe Mon Sep 17 00:00:00 2001 From: Frederik Schnack Date: Mon, 28 Sep 2026 14:30:16 +0200 Subject: [PATCH 08/22] Remove package-level wildcard exports Empty every non-API package initializer and import internal dependencies from their defining modules. Migrate tests and documentation to sympde.api, and break the hidden mapping/derivatives import cycle. BREAKING CHANGE: public objects are no longer re-exported from sympde or its subpackage namespaces. Import user-facing objects from sympde.api or import implementation objects from their defining modules.

It can be defined as follows: - -.. code-block:: python - - from sympde.api import grad, div - from sympde.api import FunctionSpace - from sympde.api import Field - from sympde.api import FunctionForm - from sympy import cos, pi - - V = FunctionSpace('V', ldim=1) - F = Field('F', space=V) - - x = V.coordinates - - b = FunctionForm(div(grad(F-cos(2*pi*x)))) - -Evaluation -^^^^^^^^^^ - -The purpose of **sympde** is to declare objects that are needed to write an abstract mathematical model for problems involving partial differential equations. It does not provide any discretization. However, it provides you also with algorithms to manipulate the symbolic expressions. -For example, when using *generic* operators such as **grad** or **div**, the expression is not evaluated. For this reason, **sympde** provides the function **evaluate** that allows you to transform your expression into atomic operators such as **dx**, **dy**, **dz**. In the following example, we *evaluate* the Laplace operator: - -.. code-block:: python - - from sympde.api import grad, dot - from sympde.api import FunctionSpace - from sympde.api import TestFunction - from sympde.api import BilinearForm - from sympde.api import evaluate - - V = FunctionSpace('V', ldim=2) - U = FunctionSpace('U', ldim=2) - - v = TestFunction(V, name='v') - u = TestFunction(U, name='u') - - a = BilinearForm((v,u), dot(grad(v), grad(u)) + v*u) - print(evaluate(a)) - -The result is the following expression: - -.. code-block:: python - - >>> u_x*v_x + u_y*v_y + u*v - -You can then use this expression inside your code generation module to define the weak form associated to the bilinear form. What **sympde** does is the following: - -* converts generic operators such as **grad** or **div** to their atomic expressions - -* converts an atomic expression like **dx(u)** to **u_x** which can be used directly inside your python code (kernel of finite elements for example) - -If you only want to convert the generic operators into atomic operators, then you may use the **atomize** function: - -.. code-block:: python - - from sympde.api import grad, dot - from sympde.api import FunctionSpace - from sympde.api import TestFunction - from sympde.api import BilinearForm - from sympde.api import atomize - - V = FunctionSpace('V', ldim=2) - U = FunctionSpace('U', ldim=2) - - v = TestFunction(V, name='v') - u = TestFunction(U, name='u') - - a = BilinearForm((v,u), dot(grad(v), grad(u)) + v*u) - print(atomize(a.expr)) - -The result is then: - -.. code-block:: python - - >>> u*v + dx(u)*dx(v) + dy(u)*dy(v) - -Notice that **atomize** is a low level function and is called inside **evaluate**. For this reason, **atomize** only operates on the expression of **sympde** forms. +Mappings turn logical domains into physical domains. Multiple patches can be +joined by declaring their connected sides and orientation. See the executable +:doc:`examples/index` for analytical mappings, interface forms, exterior +calculus, and nonlinear linearization.
