qui conviene aggiungere anche tutti i .last
e .out
così da non averli anche nella PR, insieme a tutta la cartella backupres

anche questo file forse si può eliminare dalla PR

qui, ma anche nelle funzioni successive, per qualche motivo che non ricordo non ho specificato il tipo di U
e k
, ma andrebbe fatto. A occhio mi sembrano due Array{Float,1}

qui puoi usare U43
e calcolare g1
come
g1 = sqrt(1.0 - v1.Ac / (U43*U[4]))

ovviamente g
va definita dopo U

intendo dire che le linee da 49 a 54 vanno riorganizzate come
U43 = U[4]*U[4]*U[4]
g1 = sqrt(1.0 - v1.Ac / (U43*U[4]))
U53 = U[5]*U[5]*U[5]
g2 = sqrt(1.0 - v2.Ac/ (U53*U[5]))
U63 = U[6]*U[6]*U[6]
g3 = sqrt(1.0 - v3.Ac/U63*U[6])

e dato che qui si ricalcola U[4]*U43
, conviene definire una variabile U44
per questo valore in modo da calcolarla una volta sola

v2 = vessels[2] # MODIFIED THIS LINE | ||

in generale *
é più veloce di ^
, quindi puoi riscrivere come v1.Ac/(U[4]*U[4]*U[4]*U[4])
in generale se usi direttamente 1.0
invece di 1
, eviti la conversione durante l'esecuzione

questo dovrebbe andare dopo l'end

cambiando la definizione di questa funzione alcuni test non passano:
LoadError: MethodError: no method matching waveSpeed(::Float64, ::Float64)
Closest candidates are:
waveSpeed(::Float64, ::Float64, !Matched::Float64)
per semplificare, puoi dare a Ac
un valore di default (direi 0.0
) che viene usato nel caso in cui la funzione sia chiamata senza quell'argomento
function waveSpeed(A::Float64, gamma::Float64, Ac::Float64 = 0.0)

oppure cambi i test aggiungendo Ac
nella chiamata

@ibenemerito88 occhio che il return e' sempre dentro l'ultimo else
(in teoria julia dovrebbe essere abbastanza intelligente da fare il return di gamma_profile
anche per linea 591...ma non mi affiderei troppo a queste proprieta' esoteriche del linguaggio)

(sicuri che pi
non ci vada? tutta la validazione della tesi e' stata fatta in quel modo)
Extension of openBF for studying the effects of arterial catheters on the blood flow in elastic vessels. The equations have been updated (modification to flux and its gradient, source term, wave speed, Riemann invariants), as well as the conditions for junction, bifucation and anastomosis.
Windkessel boundary conditions are not supported, reflections are.
Tests for junctions and bifurcations have been included but need to be improved. Test for anastomosis is still missing.
