Model dimensions too large for DELWAQ

Hello everyone,
I'm trying to set up a water quality simulation coupled to the results of a Delft3D-Flow simulation. When I run the preprocessor delwaq1 I get the following error message:
ERROR  : real array is too big. Unable to create pointer
I found the related passage in the source code in file dhmmra.f, it's due to an integer overflow of the variable counting the size of an array. If I change the variable to an 8 byte integer, delwaq1 runs without an error. But of course, delwaq2 crashes because the array is used in many other parts of the program.
Is there any way to avoid this error and get DELWAQ to run with large models?
Best regards
Stefan

I already found a solution. There is a branch in the repository for big DELWAQ models.

Beton pracetak memiliki beberapa kelebihan dibanding material lain, antara lain : kemudahan pengolahan, kemudahan instalasi, bebas polusi suara dan debu, serta hemat waktu. Pengolahan pracetak dapat membuat semua bagian bangunan menjadi panel beton. Produk pracetak dapat berupa kolom, balok, panel dinding hingga saluran air untuk drainase. Fabrikasi harga pagar panel beton dilakukan di bengkel atau pabrik, sedangkan untuk penempatan dan penyambungannya dilakukan di lapangan dengan proses cast in situ.
